Here is what I have found. ID stamped on the tube is (T or L)AC 57 2402
on the pumpkin is H (O or 8 or 6)20

I was told Camero. it is going into my 54 Chev and I need to get brakes for this but I dont know what year camero to buy them for and any other info I will need. How do I find out a ratio? and Is this a C clip rear? I will need to pull the axles out if i need to change the backing plates. Can I put the orriginal 54 drum brakes, backing plate and all on this rear?
Thank you for the help!!!

Post pictures and measurements. The first gen Camaro (no E) rear end is 60 inches wide and the second gen Camaro rear end is 61 inches wide. The '67 to '70 Camaro rear end is a 8.2 10 bolt and the '71 to '81 Camaro rear end is the 8.5 10 bolt. Spring perhces are different for mono and multi leaf springs. You can not use the '54 brakes on these rear ends, and they are all c clip rear ends. Chevy didn't use anything other than c clip axles in their cars from '65 and up.

Here is a page on identifying the GM 10 bolt rear end. BTW, the rear end is just a "10 bolt", not anything to do w/"main", main is referring to the bottom end of an engine, like 2-bolt main or 4-bolt main.

So measuring the distance from the backing plate to axle where the drum goes and it is a 1/4 inch different. Is this why I can not retain the original 54 brakes?
When I recieved this axle it had only bacing plates and no spring perches. Where am I measuring for the 60"s since the drumbs are missing?
Withour knowing what vehicle this rear came from how can I come up with brakes for this rear on a budget? I realize I can get a disc conversion but they are costly. Is there a jumk yard set up that I can use my already installed backing plates?
Or a cheap set up I can put together at the parts store that will fit the existing backing plate on my rear.

Axle flange to axle flange, where the wheels bolt on, should be 60 inches for a first gen Camaro. The first gen Camaro brakes are the same as all 8.2 10 bolt, 12 bolt and 8.5 10 bolt Chevy brakes up into the late '70s. You can't use the '54 brakes because the housing ends are different and they will not bolt on.

That makes sence. Thank you

There's a chance the backing plates could be redrilled to match the later housing. But parts availability will be better keeping the later brakes on the housing IMHO.

Axle hang out on the Camaro rear end will be 2.75 inches. I don't know what the truck axle hang out is, but if it doesn't match then the brakes will still not work. This would have to be measured before going any farther.

Got it, thanks.
