63-64 Bump Stop Mod

63-64 Disk Conversion – Bump Stop Mod


To install disk brakes on a 63-64 whether it being factory style control arms or our full coilover kit, you’ll have to cut and modify the bump stop bracket to clear the new disk brake caliper. 


Cut factory drum bump stop bracket flush with the out side of the frame rail.

***hint: if you remove the lower portion of the bump stop bracket, you can use a factory 65-74 Bump Stop (SG-31) and skip modifying the 63-64 bump stop below.

Insert in the factory hole with just enough room for an open end wrench

Make sure you painted all your cut surfaces for rust prevention. Otherwise you are now ready to install disk brake t-arms.
