Need to go junkyardin very soon and was hoping to find out an "ideal" overall length ahead of time. I don't want to have to get axle tubes shortened and etc. if I can possibly avoid it. Are there any GM units you'd also recommend? Ideally I'd like to find a car or truck with an older style o.d. trans, a driveshaft and rear unit but one of my buddies suggested staying away from the GM rear ends because of issues welding on the bracketry. Thanks!
most are too wide for a hot rod. the narrowest 9" available was in the early broncos, 66-77, but can be a bit spendier than the wider truck axles. IIRC they are 62" WMS to WMS. an 8" from a maverick would be a good choice as well. as far as the GM stuff, the main issue is they are fugly from the rear.
I am running an early f series 9" 61 1/4" and having a set of 16" steelies widened from the inside. My tire will go above the bead line so I needed something a little wider. I believe the early bronco's are 58 or 58 1/2" wide.
This thing will be low enough where "fugly" doesn't matter one bit... what are the "other" issues though? (Fenderless... of course btw)
Is this measurment off the outside of the drum or just to the and of the tube? Thought I'd seen a few other threads that said the old-old bronco ones were ideal. thanks!
im running a 28 tudor with 10 inch radir wheels with 4 inch back space car is channeled 5 inch went with 64 1/4 inch thats drum face to drum face the housing would be 5 inch shorter flange to flange. i think later broncos have housings that are 60 1/4 flange to flange so drum to drum it would be 65 1/4 the prob with these housings is that the drivers side axle tube is longer then p*** side.
My Fav's are the 57,58 Ford wagon rears if I am not mistaken they are 54" backing plate to backing plate. The p***nger car rears had a smaller bearing whereas the wagons had the larger axle bearings like a 12 bolt GM has. I am running a 58 in my model A coupe that is channeled with 47-48 Plymouth 16" wheels and have plenty of room the top of the tire is a 1" over the deck lid.
i've got an early olds that (allegedly) came out of a model a, has the cross spring mounts already on there, trailing arms and brakes, too. what motor and trans are you using?
Can I find one of those... easily though? My buddy put a mid 60's FoMoCo 9" wagon rear unit in his Tudor and it fit's nicely... although he will have to get offset wheels as the tires are about 3/8" from the body right now as it sits... I intend to run skinnies on all four corners.
Various rear axle widths... http://www.quickperformance.com/Technical%20Info/sus_measure.htm http://www.440magnum-network.com/info/tech/rearaxle/moparrearaxle.shtml This is a good chart.... http://www.carnut.com/specs/rear.html Nine inch info.... http://www.kevinstang.com/Ninecase.htm Isn't google great????
Very early 9" rear ends like the 1957's have always been popular with hot rodders especially when the rear is visible. They are smooth and don't have the hump in the back of the housing that the later models have. I bought one for my sedan but it was too narrow. I believe its 54" backing plate to backing plate. However it did barely fit my 30 roadster body. I ended up going with a 78 truck rear for my sedan. Just under 58" wide and I have 2.5" between the back of the tire and the body. My car is heavily channelled too.
im runnin a 1982 f100 ford truck 9 inch under my car... the tires clear the body by 1 inch on eather side....perfect fit....
yes... I wish I'd have "invented" it... or at least bought stock in it early on. here was another thought... 3/4-T GM trucks from 86-94 ran these... so there's an o.d. trans, driveshaft and rear diff. I'm only going to be around 300hp-ish in a light car. So this might work with this upgrade... http://www.chevyhiperformance.com/techarticles/48518_posi_10_bolt_upgrade_install/index.html
thanks... nice car too btw... my buddy is building a 29 that looks similar and ****s at "internetting" anymore pics of it... and the eternal HAMB question... how much chop?
I am using an early Bronco rearend also. The width is just right. If you find a housing with axles they were 5 on 51/2. Plus it's a 9 inch. Parts can be found anywhere.
If you are going low enough that the top of the tire is near the beltline then you need a 65" rear end. Go with a Ford 9" from a late 70's or 80's truck. 65" outside to outside. Cheap, and dont worry about the driveshaft. Chev, and Ford used 1310 size u-joints on 9"s and 700r4 ******s Need one PM me. Later ROB
i have a banjo rearend been narrowed to 55 in. wms to wms with 9 inch 28 spline axles and hot rod works axle ends. gives me later style axles and brakes and still have the banjo look. s10 rear is 54 1/2, and the 4 wheel drives are i believe 4 inches wider. i forgot to mentione i am running fenders on my A.
How much pinion offset is "too much"? I think I found an ideal 9" for my "A" the way it will need to sit in the body and adding for the wheel and tire for clearance... but the pinion offset from center is around 3-4" to one side... no big deal... or shouldn't I bother? How much is too much?
