Thanks again for the positive responses. Lots of work but well worth the effort.
I've had a couple member ask about the 3 point seat belts up front so thought I would post information here if OK.
I cut into the B Pillar and stuck a piece of square key stock about 10" long in the post. Plug welded the key stock, then rewelded the metal piece back into place.
The seat belts were purchased from Morris Concepts. MCSB1-5A-BK
with the lift buckles. Also got the adjustable inside belt for up front in case the seat was moved forward or back from my spot so the 3 point belt felt right for whoever was driving.
The back seat belts are just the matching lap belts with lift buckles. Billy Morris and wife Robin are great people to work with. If something isn't right or you change your mind and want a rework on something, they have always been #1 in customer satisfaction.
This is what the lower retract looks like.
