Severely Toed Out

View attachment 1715950473

Could be a B-Body K-member, not sure it will bolt up but you did say you changed it?
Sorry George...have you ever worked on an A and a B body car? The frame rails are further apart on a B body. The k members will not fit from chassis to chassis.

I would be looking at the UPPER control arm alignment cams, the strut rods and maybe....the sleeve in the K member that the LCA pin slides through. They can get ovalled out and make the lower control arm move all over the place.
One more thing....are the upper control arms on the correct side? They are LEFT and RIGHT.
