I bought a 8.5 axle cut down to bolt into a 62-67 but I need new brake pads, springs, brake cylinders, drums, etc... I don't know what this rear was out of to get the correct parts. Have any ideas?

Axle Code:

5PM G313 2

What's the housing casting date? That would help narrow it down (no pun intended). ;)

The only "PM" code I know of was for 3.23 open in a 1978 Camaro.

Hmmm... I'll see when I get home. Should the brake parts interchange through the years?

Here's the code on the tube. 5PM G313 2


Here's the code on one side of the diff.


Here's the code on the other side of the diff.


Any idea what posi this is? Standard GM? Is it rebuildable?


Richmond Gear.


Welded tubes.



Also, I smell some WD-40 in there. That can't be good for the discs. What should I do? Thanks. :eek: --Damon

Hmmm... The Richmond gear site says this is a 4.56 not a 4.88. Guess this guy had no clue what he was selling.:confused:

sorry for the thread hijack, but were did you purchase it from? is narrowed down to fit larger wheels in the back? The reason I ask is I have a 63 and want to replace the rear end on it with a larger and posi unit.


thank you, Cesar.

Anybody know if the yoke on the diff will match up with the u-joint size of my driveshaft? I know the diff is about an inch or inch & a quarter longer, but I'm going with split monos with an inch setback.

Original question?

Parts for brakes?

You should be able to use the backing plate and the brakes from your current car.

If it has rear disc conversion, take some pics and post. I will try to ID.

Thanks Al. I'm going to try and sell the rear complete(old one). A few people told me just to match the pad and drum, everything else should be the same. Any thoughts?

I'm pretty sure they use the same brakes shoes. Everything should be the same. You can double check by measuring the drums, but If you went to the store I bet the part numbers would be the same for rear brakes for both the Nova and Camaro.

Well the problem is it's not a camaro rear. It's a '79 or '80 GM or BOP of some sort. That's what I've been searching the net for. I can't figure out what this came out of in '79 or '80. I took the drums off my 67 and it looks like the shoes and drums are the same. Visually, everything else looks the same also.

very true. GM drum brakes are simple. A good parts man just needs the drum dia and shoe width and should be able to come up with everthing. One of the most comon is 9.5'' dia X 2'' wide the shoe number is 472

The WD40 smell is nothing.

What else are you looking to get for the rear?

The guy had the rear outside with the diff cover loose, so there was a little surface rust in a few places. Smells like he gave it a coat of WD40 to cut the moisture. I just didn't think it was a good idea, but it sounds like it should be ok.

All I need is to rebuild the brakes and get a diff cover. I hear TA is the best, but can't seem to locate them. Might just opt for the Moser piece. Thanks. :D
