Pfreen and or Tony, Would appreciate any pictures you may have of a TCS showing this area upholstered. Also interested in how the headliner terminates at the windshield, A posts, etc.. Thanks
Headliner and A pillar trim are just folded over the flange and glued in place. Crude, I know.
I used black door edge trim to finish it off and lock it in place on the headliner; on the A pillar, to keep it looking a bit more 'substantial', I filled in the pillar with expanding foam (sorry, no photos), trimmed it flat, then just wrapped the upholstery (actually a couple scraps of Connolly hide I had left over from my Turboesprit interior recovery before Connolly went out of business) around the flange and glued in place.
Front of the dash pad, I trimmed back the fiberglass to fit (freed up the vinyl cover first...), when it was satisfactory, I folded over the vinyl trim, and used more edge molding to clamp the edge.
See photos below of 693R...too damn cold (-4 here in Fall River), so NOT going down to the garage to grab a photo...)
