Well I have new progress to show. It is time to install the interior and part of that is remodeling in 3PT seatbelts and 72 E-body bucket seats. After installing the rear seat back and bottom, I had to pull the newly installed headliner back at the upper 3 PT seatbelt attachment points. Then I had to add 7/16-20 NF backing nuts for the upper attachment and reinstall the headliner. Then I had to drill and tap a new lower attachment point for the fixed belt. (the retractor installed in the factory SB attachment points on both sides of the seats) After remodeling the 67 seat tracks onto the 72 seats I trial fitted everything to make sure there are no conflicts. The photos below show the result but not the pain and grief involved in accomplishing said work. Thanks for looking------------------DR-----------------:-)
