input on quickchange rearends

All new to the quickchange rearend have a model a rearend and wanting to put a quickchange center section in the middle any suggestions on who to go through for a new center section or any options to consider I am a alliance member and any input would be great.

 

The rearend itself will be going under a 30 sedan would like to go brand new.

 

What type of horsepower are you running? There are a few options - it kind of depends on what you intend to do with it, the look you want, etc.. If you don't know much about it, then a great place to talk to is Hotrod Works - or Cyclone (I think they are Alliance vendors).

Here are some links:

You might also check out Winters - they make a bunch of QC's . . . probably the biggest mfgr in the business today. They can supply you a complete rear - though probably not setup with your parts.

You're going to spend somewhere around $2,000 to $3,000 . . . depending on the options, differential, etc..

Best of luck . . .

There are other guys as well -

 

I think that there is a guy in New Zealand who makes new Model A quick change center sections.

You might consider upgrading to a 37-40 axle. It will be stronger and V8 quick change units are more available than Model A. This is discussed in the book "How to Build a Traditional Ford Hot Rod" by Mike Bishop and Vern Tardell.

 

I have four years of hammering mine with a 322 GMC Inline with four speed in my A.
Been a great unit !
I bought it from **** Spadaro
www.****spadaro.com

Good pricing at $ 1395 and they have helped me any time i needed the help. ****s a hamber as well....

 

Agreed, but make sure you ask for the smooth cover.

 

If you are talking Halibrand type, be aware that the Model A to 1934 banjo is smaller diameter than the later 1935-1948 banjos. The Halibrand type you need is equivalent to the 'Model A/Midget' Type 101 with 9" bolt circle for the side bells. The later type 'V8 Type 201' quick change has 9.25" diameter bolt circle and a snout at the pinion. The Type 101 is narrower, shorter but looks similar to the type 201.

Type 101 (Model A/Sprint) 13-3/4"L, 3-1/4"W, 9.00" PCD.

Type 201 (V8) 15-3/4"L, 3-3/4"W, 9-1/4"" PCD

Type 101 good up to 300hp, Type 201 400 hp, as a rule of thumb.

Here's a few photos of the two. The smaller dimensions are always the Model A/Midget Type 101.

 

Breaking it down to you in simple terms.

See those pictures above? The pinion is part of the center section on the top ones. Therefore people say that the pinion is "supported" because it rides in that built in area in the center section.

On a Model A banjo center, the pinion is NOT supported in a "cage" in the center section. The pinion is pressed onto the end of the drive shaft but nothing supports it on the gear side. With more horsepower than the Model A 4 cyl, the pinion will want to walk out of the ring gear.

With the later center sections, the pinion is supported in place and less prone to want to walk out of the ring gear. Also, quick changes like the one pictured at the top above and for the later axles are MUCH more available. You have more choices and price points.

Therefore a Quick change center section for a model A axle is VERY different from the others that people are telling you are available new.

Right now, the only one I know of that is new and fits a stock Model A axle is the New Zealand quickchange. There could be more though that I don't know about for midget application. (he's asking for new guys, not rare originals)

Hope this helps and makes sense.

 

Here is the Kiwi's guy info.

If you don't want to dump a load of horsepower through the qc, then this is the easiest option, because you can use the rest of your setup as is.
These are a well made qc (Vern Tardel recommended them to me when I was looking) and he sends a lot of them to the US.

 

a quick change takes 50 horse power ,,,if it matters

 

And an original A has what 45? That leaves you with a negative. Does it make the car go backwards?

 

Ive been considering one for my AV8 myself are the Kiwi's open drive?

 

Not sure if he does open drive - Derek's email is antiqueford@xtra.co.nz.

If he doesn't do it...you can get conversions
