Are the SPINDLES interchangeable between disc and drum brakes? In other worlds, the parts between the ball joints.
The drivers side spindle on Project Olds-Camino is mangled, looks like it suffered bearing failure sometime in the past. Looks like they cut the bearing off with a cutoff wheel. The inner bearing won’t side off as it should, it’s going to take a bearing puller to remove.
My question, I have access to a cheap A body parts car with drum brakes. Can I remove the spindle from the drum brake car, and transfer the caliper mounting stuff the the drum brake spindle? Im assuming you can, I have seen the aftermarket disc brake conversions, it appears that’s exactly what they consist of.
If you are talking about 1964-72 A-body, no they are not the same. Common sense should tell you that if they were the same, there would be no reason for aftermarket disc brake spindles to exist.
The difference is in the depth of the top backing plate/ caliper mounting boss. Drum brake cars have a much deeper/ taller boss so that all three mounting points are the same hieght. Disc brake spindles have that boss machined down. If you have access to a mill and know how to use it, you can macine the drum spindles to work correctly with disc brakes. Otherwise, it will be easier just to buy a reproduction set.

The Wilwood conversion kit can be used on both disc and drum spindles. It has a spacer so the caliper bracket sits correctly when used on a disc spindle.
