AV8 banjo rear axle choice ?

[Jack 34pu]

I have found a banjo rear out of a late 30's Ford that has the radius rods bolted to the bottom of the brake backing plates and to the closed drive shaft housing. I've been told these are the ones to use for an AV8 project. Will the width of the axles fit under Model A fenders? If not, what banjo rear do you suggest for the AV8 project?

Maybe post this on the EV8 board or the HAMB. JMO Do you have Tardel's book, wealth of info but evidently some of the dimensions are not correct.

Jack,
What kind of wheels do you have in mind?

The drive shaft length would be an important consideration to me. I put a flathead in a model A back in the sixties with the model A backend. the engine sit way back because of the shorter V8 transmission. If the drive shaft had been six inches or so longer it would have made a better swap. then you have to consider that the rear spring is behind the axle on the V8 backends. you will probably need
to cut the frame in the rear and add another slightly longer section of model A frame and crossmember, maybe stack it on top of the present frame and box it,this would lower it a few inches in the process.

37-41 rears are the ones for a AV8..but not sure about fender clearence the 37-41 are about 2 inches wider than 28-31 rears..like FLAMINGO said get the Tardel book wealth of info..

I'm working on building a AV8 and was going to use a 35-36 ford banjo, they're more narrow then the later banjo's but you run into the problem with the drive shaft being the wrong splines if you want to run a higher ring gear & pinion.

So what I did was get away from the whole banjo rear and went open drive with a 39 transmission and a 70 bronco rear. The 66-76 bronco rears are narrow and only about a inch wider then the original Model A banjo and a lot more user friendly with gear ratios and strength behind higher horse power V8's.

Why not just use the Model A rear axle. I have used the Model A rear axle on 4 A V8s. That is what is in my A Roadster V8 that I have now. I use to have a 4 cylinder with a 455 olds head on it. I used it for hill climbs, the rear axle never broke. The 4 cylinder had more torque than the V8 has.
