Moved on to fabricate support bracket to hold the rear seat retractor (bolted down through the package shelf). Took steel angle from a bed frame. Cut a notch into the side to enable bending to shape desired. Then welded a patch to reinforce the cut. First photo just shows the bracket for the passenger side. Second shows the install on the drivers side. Shiny spot in the photo is reflecting light off the patch. A little to the right of the patch, a slither of the nut is visible. This is a dry fit. Needs to come out for painting. Two bolts on each side go through the raised flange of the wheelwell. I don’t know how strong this bracket will be in a head on collision, but it will be a heck of a lot stronger than relying only on the package sheet metal.
