The Stovebolt Site Forums The Shop Area Driveline hard to find brake drum

I recently acquired a 68 GMC half ton. The rear brake drums are shot. My local auto parts stores keep trying to sell me the wrong brake drums.

Mine are 3.5" deep, the ones available are 3.0" deep.

Anyone know where I can get two of the deep style drums? Napa, O'Reilly and Pep Boys all come up with the wrong ones.

Thanks in advance, I am in Los Angeles, California

....are you sure no one has previously changed the rear end on your truck?
Can you find some numbers on the differential and let us help you identify just what you have?

Welcome to the Stovebolt. You will find many bolters in Ca. and maybe in your area.

Hy Kit Maira, welcome, could you give us a bit more information please, inside diameter of brake drum, width of brake lining, and number of studs that hold the wheels on?

GMC's used Spicer rear ends and the drums have an offset on the face.
To my knowledge the drums are not available.
You may want to change to a Chev rear end.

They are 11 inch in diameter, the linings look to be 2 inch and there are 6 lugs.
Thanks,

Thanks. I hope that is not the case. Perhaps there are some used drums out there. I would hate to have to change out the rear end a week after I bought the truck. It's a leaf spring Dana rear end.

If its a Dana axle its likely that the brakes are Bendix.
I've not done any research but you could look at 70's Wagoneer's and 1/2 Jeep trucks which would also be 6 lug.

Thanks. I had the day off today, (Easter Monday) so I drove around to all the junkyards in the area. No luck there, but Valley Friction Materials in North Hollywood just called me back. They may have located a pair in Wilmington. If all goes well, I should have them by Wednesday. Thanks to the folks who answered my post, good to know there is a community looking out for me.

Check with Early Classic Enterprises http://www.earlyclassic.com.
You may have the heavy duty rear brake option on your truck. They will know about it as they sell a kit (including the drums) that allows one to upgrade standard duty brakes.

Does this look like the right one?
Or this one maybe?

Those are both the 3" high drums. Mine is 3.5". I was able to locate one NOS drum through Valley Friction Materials. I will probably use my old scored drum temporarily until I find another. So... I'm still looking.

Thanks,

I spoke with them, was told that they didn't have anything for the Dana rear end. Thanks,
