Rear axle for AD truck

Hi Guy's,

I am building a rod along the same lines as Centreline. He recommended using a '78 Camaro rear axle. I have the chance of buying one from a '73 Firebird Bullnose. Are they at all similar or should i avoid it?

We are not exactly spoilt for choice in the UK.

As far as I know all the Firebird and Camaro rears of the 70s vintage should be the same width and have the same spring perches. Someone please correct me if I'm wrong.

Centerline

That's my concept of those cars - made of the same parts except for different rubber front and back bumpers and different name plates.

Both cars used the GM 8.5 inch 10-bolt axle from 73 to 81, it should have the exact same spring perches and everything else in the same measured dimensions.

How many ponies can that rear end handle? I'm building a 400hp+ engine to drop in a '41 Chevy p/u and been looking at my options. Any suggestions?

Darren, Did you get that rear from the camaro. I used one from a 75 and I had to remove all of the hardware that was welded to the axle and place new spring pads for the narrow spring in my 55 1st series, but if you are changing the springs and hangers it should fit. The width is correct but as mentioned a nova or Monte Carlo is 1 to 2 " narrower.

Hi Solidaxel,

I am fitting a 4 bar setup with bags so all hardware will go anyway. Cheers for your input.

Darren.

Hi Solidaxel,
I am using the TH350 that came from my old C10. Just got a Camaro backend today, plus dropped spindles and an Impala steering column in exchange for truck bits i don't need. Will order Mustang ll front crossmember soon.

Cheers, Darren.
