Back to work on it.
Realized there would never be a better time to make good solid anchors for the shoulder harness top mounting bolt. Much better than just drilling a hole and lowering the little kit piece down with a string.
Question: There is a hole (aprox 5/16)in the door frame below the top rear corner, and a matching cut out on the new inner panel and a gap in the windlace track.
What is it for? I don't remember anything in it and think it was covered by the windlace. Don't want to cover something up or forget something.
Could be the perfect place for the mount (was thinking an inch higher).
Also realized that I can install Dynamat on the roof and rear panel before I weld the inner panel in.
