I thought about tapering the hole if it isn't too much to where it weakens it. Thanks for the heads up on the 74 spindle. When I looked up the ball joint for it, I saw it was different.
I'm looking for 70 - 73 disc brake spindles. Doesn't matter what car they are from as long as it's a C body. I think 70 - 73 11 3/4" pin caliper bracket holes should all be the same.
Just send me a PM.... Thanks
