Front drums for 1970 k20 help - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Krex · 05-17-2015, 10:41 PM

Hello I can not seem to find a place to buy some new front drums for my k20 truck it's a 1970 with 8 lugs and the shoes should be 12x2 any help would be great also I need to get rear drums for my eaton rear diff. Rear you have the bearings inside the axles. I prefer if there is a conversion so I don't have to pull axles every time. Thanks for the help guys.

unless things have changed in the last few years, drums for 4x4s are nearly impossible to locate. my advice is swap the front to a later model with disc brakes and use a matching ratio 14 bolt in the rear. some newer 14 bolts have disc brakes if you want disc all-around.

Thanks for the help so far... I know it's tough. I don't have the extra cash for a convert to disk right now.

I had the same issue with my 1970 k20 gmc suburban. Even went as far as trying to get some made. Then a buddy at oreillys in tn found me a drum made for 1994-1999 dodge van! Fits perfectly with no machining or adapters! I will look for the part number and post it. They were about $50 each new

If you call your local O'Reilly store and ask for the rear drum from a 1994-99 dodge 3/4 or 1 ton van you will have front rotors again!

When I said Rotors I meant to say brakes sorry.
