Hot Rods Rear ends for Model A? What ones are you using?

Hello hambers I wanted to say thank you for your help on my past threads and I wanted to start a new thread and ask what rear ends are you running in your model a's?

I have a 30/31 coupe and a 30/31 pu coupe has mild 302 that i plan to pump up before to long and pu has a 368 lincoln y block

both are fenderless...maybe fenders later....

I wanted to ask what rear ends you are running?and from what year/make/model donor vehicle you got them out of =)

and what do they measure backing to backing and drum face to drum face?

and what year and make model a do you have

any help would be appreciated and have a great day

thanks hamb

 

I'm using a 9" ford from a 57 sunliner in my 30 sedan. Fit perfect with fenders.

 

I'm running a 31 spline axle, 9" ford , out of a 1978 ford truck in my 28 model A sedan . I don't think I could have asked for a better fit . I got about a 1 1/2" space on either side of the body . And she lays low !! About 58" or 59" backing plate to backing plate .With L-78 x15 mounted on mid 50's caddy wheels .

 

I'm running a 9" off a '58 Ford Ranch wagon. It fits with and without fenders.

 

'48 Ford F1 dana/spicer model 41. Geared pretty low,but running 29in tall rear tires.

 

My 1930 roadster is a falcon 8", my 1930 5 window had a 68 mustang 8", the 1929 truck we used an after market 33 spline spooled 9" salvaged from a wrecked 73 chevy truck, and lastly (yes its a TT) we used a 28 spline 9" from a late 60's torino/failane with 78 Toyota 1 piece duallys

 

I'm running a 9" out of a cougar.

8" from a late 60's comet here.

 

Narrowed 31 spline 9" out of a Full size Bronco.

57 Chevy rear

 

Same here.....mine's out of a 78' Ford Truck. 59" backing plate to backing plate. I have mine in a 30' Model A Tudor. I've got about 1 1/2" space on either side. It's pretty low. I have 40 Merc. wheels (5" wide) with Tall ass Firestone bias plias. Fits perfect without any modifications. It has a heavy duty housing. 5 on 5 1/2 bolt pattern. I paid $100 bucks for it.

Halibrand/'40 Ford under a 31 A roadster...(eventually...)

 

S10 with 1" adapters to run 5 1/2" bolt pattern.......

 

Im running an 8 inch! In my opinion they are prefect for model A's. Also think about it, you dont really want a spool or locker with a model A. They are so light, it would be very dangerous when you let the smoke out of the rears!

 

I have a '29 Tudor Sedan. I'm running an 8.8 from a '92 Mustang and it's been converted to 5 lugs (formerly 4 lugs).

 

I used a Mavrick 5 lug 8" fit perfect

 

I'm using a first generation Bronco 9" , running without fenders

 

I'm using a 1979 Ford LTD wagon 8.5 rear axle, and I was able to put in a Mustang 8.8 locker and 3.27 gears into. it clears the body sides just fine on a channeled car (no fenders,obviously)

 

i heard all the stories! your rear end will come around in the rain. (Cool) It will plow straight ahead through corners! It'll tear the rear tires up blah, blah, blah.
i ran spool in my 29 for over 2 years. No problems. 2180lbs with my big ass in it. i had everything on the back from 15" wide tires to skinny bias ply silvertowns. drove it 6o miles one day in a total down pour in a cancer run for an ABATE brother. Rearend was always right there behind me. never did pass me up.
Heres a shot at the Shelton drags. Held pretty straight for me even after the smoke let up.
Question would be how do you get smoke out of the rears without a locker /spool hmmm

Bottom line: ya drive it like what it is.

 

I'm using an 8 inch rear from a '65 Mustang.Can't recall the width,but it's pretty much perfect for an 'A'.Unfortunately,I've had to use adaptors to get a 5 on 5 1/2 bolt pattern.

I have a S10 rear end with 7 inch wheels. It is tad to wide. I plan trying 15x6 steel wheels with a four inch back space.

 

I've an 8" open diff from a 70 mustang. 2.79:1 It's sitting behind a 430hp Pontaic 400 and a Th400 trans. Guess what the weak link is?

 

Got a '58 Fairlane 9" in my '31 coupe.51" between the backing plates,56" flange width.It's fenderless and has some good meats on it,fits well.We put a 8" in my pops '31 full fendered roadster.49" backing plate to backing plate and 54" flange width out of a '70's Maverick.These rears are getting scarce and pricey though.I have measured 8.8's out of Ranger pick-ups to be 52" between the plates.Good width,funky driveshaft flange plate however.

 

No longer have an A but nothing looks better than a quickchange out back.

By the way for the guys that used 78 ford truck rear ends, did you get the 9'' not the dana rear? and out of a f100,f150 not an f250?

and would a 73-79 pickup have the same width rear end?

thank you hambers
