hot rod model a rear end

HI JUST BOUGHT A NEW AFTER MARKET MODEL A FRAME..IT HAS A 32 FRONT CROSS MEMBER AND RAISED 3 INCHES IN THE REAR.
I AM USING A 31 SEDAN BODY.
COULD SOME ONE TELL ME WHAT TYPE OF REAR END I SHOULD PUT IN IT? WHAT I AM LOOKIN FOR IS HOW WIDE IT SHOULD BE..
(OUT SIDE TO OUT SIDE)
I AM NOT GOING TO RUN FENDERS.
BUT IT WILL BE A HIGH BOY STYLE.
I HAVE A 70 NOVA REAR END AND A S10 4X4 REAR END WILL ONE OF THESE WORK?
IF NOT WHAT SHOULD I LOOK FOR??????
THANKS FOR YOUR HELP...

re: hot rod model a rear end

Most Model A guys like to run a Ford rear end......either a 8 inch series or the stronger 9 inch. I prefer the 9 inch myself. 1957 to 1959 Ford cars have a 9 inch series rear end that is 58 inch....measured the way you described.....

The 9 inch is " The choice " of most rodders because of the strength and the ease of changing gears. The parts availability is GREAT Also...

I have a early Ford Bronco 9 inch series rear en under my 32 Ford roadster....it is 58 inches also but has the 5 on 5.5 wheel pattern.......which I wanted.....to match my 56 F-100 front brakes...

On my 32 3W........under construction..I used a 57 Ford 9 inch...with the big axle bearings.....look at my project journal for a few " under construction photos "

The 70 Nova rear should measure out at 60 inches....and the S-10 4x4 rear end is most likely too narrow. I do not like either......because of the way the gear is installed.....and the axle bearings are in the tubes.....not on the axle shafts....but that is just me......

re: hot rod model a rear end

56 wide wheel to wheel seems to be a little better for an A.

Chevy rears are fine. Axles and wheel bearings are no problem especially with a lightweight A.

Who ever changes gears in a Ford 8 or 9 more than once in a car's life anyway? Not many of us drive to the strip, swap rears, race, swap back to come home.... In my opinion that is irrelavent.
