What fits, late to early front end parts to swap?

I did indeed narrow a later slant 6 k-frame to use in an early A body, and then moved the motor mounts because the early A body had the k-frame in a different location front to back. Even still have the stupid k-frame.

When I built it, I put an aftermarket sway bar in it and it sure looked like a win. My plan was to use naked LCA’s and fab my own mounts. I think the better plan now would be to find some 90 degree ball joint style sway bar links and bolt them through the side of the LCA.
