Just in case, I have one of those bells (1 ton ford truck) You need 2 lefts .Ialso used the 3/4 ton differential with late model side gears so as to accept modern axles. You weld on modern bearing housing.
Kiwi Kev, It's not over till the fat lady sings or should I say QC whines, I have the water waiting in the cup for those decals.....
I have located a Halibrand QC , a 10 bolt with what looks like a 202 casting number. What model is this? Should I grab it? Thanks, Loslobo
All very good articles on the V8 quick change, but how about the Champ with 12 bolt side plates that adapt Early Ford Axle bells for use in a hot rod with Horsepower? I have tried to find a carrier that will work in this set up but to no avail. I was told that a 3/4 ton 38/52 Ford truck would work, so I purhcased two of them and they are two wide for the above set up. Does anyone know what they used as I have a complete set up waiting for my roadster. Here are the parts Halibrand 12 bolt Champ case Halibrand 12 bolt side plates H852A 40 Ford axle bells with 9 inch Ford big bearing housing welded on Buick Backing plates with Finned Buick drums Carrier, differential required, unknown at this time Any assistance would be appreciated.

This is what I have done it the past and have learned the hard way. One: do not use a detroit locker. They are sensitive to tire size (stagger) and if you are not within 1/4 of an inch it will pick up the different rotation and will be trying to lock.....clackety clack crap noise......not fun after awhile. Find a Gold track, DPI (Dan press industries) Sierra industries differential for a quick change. It is a gear driven (spur gear) locking rear end. They are so efficient that many tracks outlawed them. They come up on the internet pretty often. Buy one of them. Make sure it is for a champ style 10inch ring gear and in pretty good shape. New they are 800-1200 but on the internet you can find them for 200-600. Then buy or borrow a spool for a quick change. I have one you can borrow. These are made to fit right into the early ford side bells and have no clearance issues. You lay it out and take meaurments and then translate that onto your gold track. Carve it down to match the dimensions of the spool. It is not very elaborate. They are the most awesome rear ends. Both tires spin when you want them to. You can adjust the tension in them for full tight at 25% or any load you want. The manual you get online tells you how to do it. We had it behind a very healthy small block and beat the heck out of it and never had any problems. i used early ford bells with New 9inch ford housing ends welded on. Had some new axles made. Has been an awesome set up.
Thanks, I have seen DPI, and several other models on ebay but did not know what to use. I will see if I can win one. Other people indicate that the current one Halibrand uses which is made here in So Cal will also work, but Speedway said not without a lot of machine work...$$1000 or so. Another fellow told me he used a 68 Jaguar differential and has two of them running in street roadsters. I like the sound of the DPI. Thanks again.
I just bought a DPI Gold Trak for 96.00$ and it is in perfect shape. Now let the carving begin. Very simple Lathe project. I will post pictures later on when I begin.
Hey Kev, if you do not win give me your address and I will send you a set of decals for your effort. Skip
Re the "Pepe" article in R&C Magazine I,m presently working on a Torrance V8 halibrand using the "Pepe" article as guidance.I am using a stock ,37 ford 378:1 ring and pinion and have found out the following info which I would like to share 1.Early ford ring and pinions aren,t a bolt in- a common misconception is that they do.The double cone and cup Ford bearing assembly does fit in the pinion tunnel of the Q.C,but it is easier to set the pinion depth using the ball-race type bearings. 2.If you do use early ford parts,the pinion will not fit the roller bearings used in hali,s (6307,s) with an i.d of 35mm-early pinions measure 38mm,so a cylindrical grinding job is required 3.I,ve found that the New Departure 307-B Max type bearings that Pepe used three of instead of two 6307,s are very hard to find in Australia these days,( I,m guessing that article is probably 30 years old now.)-so I plan to use two heavy duty 6307s and some Halibrand spacers I found at Speedway Motors.The no.for heavy duty type 6307,s is BL307-an NTN bearing 4.While the grinder is spinning,the end of the early ford pinion will have to be ground to suit the i.d of the 6304 support bearing in the rear cover.I think the measurement was about 16mm from the end of the pinion at about .675 thou to be machined off-from my memory-which has a gap or two here and there This is what I,ve found out so far,the Q.C is not re-assembled yet-hope it all works o.k!!!!!!!!!!! Oh yeah,this rear end is being fitted to my 35 Ford p/up fitted with 54 239 flathead,jeep shifted top loader,early hydraulic brakes and 35 wire wheels Hope all this info is of some help
Hello, have you started carving the DPI unit? I found out DPI is located in Petaluma, CA, so I am going to call them and see if they would interested in tooling up a differential that would work in the Champs. Pictures would be nice. What is the carrier bearing spacing on the DPI unit? A Champ with side plates for early Ford bells measures 6 7/8. Here is a picture. Lynn
when I get back from El mirage this weekend i will post some photos. i have shots of the completed rear end and of the spool and the dp diff. i dont have any carved shots. regarding having the company carve up some differentials they will not do it. I already talked to them. Regarding the company that carved up the lockers for halibrand...well they wont either. but try. and it is so simple. if you have gone this far you can do the rest. i wish i took photos of the process. maybe i will just do the one i have sitting here for a lesson to end this discussion. i can tell you i am not a machinist and it is a simple process. so my machinist said. I will try to get some photos out so others can see. It is just a busy season with race season just starting. my attention is focused on a few other things.
Hey, Pewsplace. I'm running Lynn (St.Paul, MN ) "champ style" quickie between two 3/4 ton truck side bells in my '16 T bucket. Yeh, it rides a little rough. There is a spacer that is used on the right hand carrier bearing that moves that bearing out to the bearing cup in the side bell. Speedway Motors used to sell these spacers. Same setup as Frankland. Who sells the side bell adaptors to put V-8 Housings onto Champ center sections?
I don't know of anyone who has new adapters. I purchase them on ebay, swap meets, etc. I have a fellow working on a differential and side plates for these Champ models. He should be done in about a month. Here are the 11 bolt models.
28rp............ I did exactly that with my QC almost 15 years ago. Yes the pinion has to be ground down to fit the bearings, and I did use three. Supposedly they are a Muncie 4 speed bearing. All I know is that they work, and have for 15 years. I also did the usual machine work to the ring gear and carrier. I plan on the same mods to the next one.
Pewsplace: Thanks for the info. FYI the Frankland part number as listed in the 1977 Midwest Auto catalogue for the carrier adaptor spacer is #109-2000 when using the 3/4 ton truck steel side bells. Your picture of the "Champ" squeezed between a pair of V-8 housings is just the way it ought to be. It's a winner.
I've scanned through the thread and did not see any mention of quickChange rears for IRS applications. Does anyone has experience with an IRS quickChange rear? I only know of Speedway Engineering as a provider of a quickChange IRS diff... are there any others out there? thanks dave http://www.team321.com Cocoa Beach, FL
I don't think you're going to find many people on this board who are interested in IRS. That's pretty much outdated street rod stuff, and not real popular with the traditional crowd.
I agree... I have not found many folks using IRS, but there is a wealth of knowledge on this board, so I thought I'd ask. I am confused about one statement - "that's pretty much outdated street rod stuff"... What are you referring to? what is outdated? dave http://www.team321.com Cocoa Beach FL
