67-70 and 71-72 interchangeability.. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

oldblue1968chevy · 06-12-2011, 06:12 PM

I just bought a 71 373 5 lug rearend from 68stepbed (matt).

It needs brakes etc.

Less than 2000 miles ago I redid the brakes on my 68 6 lug 373 12 bolt rearend.

Can I swap cyclinders and shoes from 1 rearend to another, or will there be issues...

Also, the drums need to be turned, I have a 2nd set of 5 lug drums that dont look that bad, let me get pics of my recent purchase...

Also, THANKS MATT for making the drive/cruise with the wife to help me out!!!

Pics comming soon, I think vintage air is on my list too haha it was hot

One lnik is a 68 rearened (whats under my truck now/motor trans etc).

The other is a 72 rearend with a 350

The P/N is the same...can anyone verify that for me (experience, not what computer says).

Suppose the cylinders are the same too?

You'll need to measure the brakes on both rearends to see if they are the same. You could get either normal or HD brakes. The shoes will be either 2 or 2 3/4 inches wide. Same shoes means parts will interchange.

so measure the width of both shoes, if they are the same they will interchange.

thanks tx firefighter!!!!

what about the cyclinders? those the same either HD or non HD?

have you compared them side by side ... that's normally the easiest way to see if two different parts are the same.
