64' Valiant steering box + bolts

Awwww man. That crack is not good. The steering box is bolted to that flange which is welded to the k frame, no plate. These K frames are known to flex in this area, that's why most people weld reinforcement plates to fully "box" that flange mount in. By the looks of it you are going to have to repair yours with some grinding and welding, or replace the K frame altogether.

Yes, the firm feel boxes are stock mopar boxes that are rebuilt with new worm gears. They will bolt right in with stock linkage and look original.

Thanks for the props Erik!

Also, you may want to check out the sector support kits from FFI as well. Might help with the steering box flex.
