I'd like to mini-tub my '67 Satellite and I'd also like to keep the back seat. The rear seatbelts anchors in that strip of metal between the inner wheelhouse and the frame. In addition, the rear seatback is up against the inner wheelhouse. What have others done to keep these items? What's a safe location to relocate the seatbelt anchor to? How should I make the seatback fit? Any information would be greatly appreciated.
