73-77 lists the same brake drum for the Abodys as the Gbodys

I recall years back, I was looking for new aluminum brake drums to replace my steel drums. no one seemed to carry them....nor were they available anywhere.
I couldn't see spending $235. @ for aluminum drums. I'd much rather put that money towards converting to rear discs. either F-body or S-10 Blazer.

Over the years I had come across aluminum drums at the junkyard. I kinda thought I'd be taking a chance buying used drums and not knowing if they'd already been over cut or cracked. Although they were probably cheap enough to risk taking a chance.

I picked up a 2000 Camaro SS axle at the UPullandPay for $125. I used the calipers, hoses, hard lines, backing plates, pbrake shoe. I replaced the pads and rotors, but I could have probably used them in a pinch. As a bonus, the axle had a Torsen and 3.73 gears that I made work in a different G-body axle. The LS1 rear swap may be more cost effective than chasing bigger drums if you can do some leg work.

The 67 Chevelle rear I have in my GP uses the same drum, thew shoes are the same size but are different design due to the bolt in wheel cylinder

i appreciate the advice. the car will be a daily driver. just trying make the most practical upgrades on the car without a huge investment. i know it's not cheap went it come to working on these cars. i think malibudave and pontiacgp advice kind of hit it on the head for me. i think that might be the way for me to go with my budget.

thanks

these brakes can also be found on 73-77 "A" body wagons. if junk yard hunting, watch out for the bolt in axles which used the larger axle flange pattern. must come from a c-clip rear end. i swapped these onto a nova axle i stuck under a 56 chevy wagon years ago. rocking set up at the time. direct bolt in with working parking brakes.
