After much consideration I decided to pull the trigger

Joe-
You mentioned an A body power steering swap. I've done it with both the factory power steering box with headers I made (very tight), and the Borgeson power steering box with TTI headers (first jig set didn't fit as well as the second drivers side they made- they changed the jig due to my notes and pictures).
I'll be happy to share info and pics as you need them.
