My 86 has some really dead trim on the carpet. Doubt you could ever find it. Adaptation/modification for the win. Same for the interior kick panels. Might find something somewhere, but doing your own might be cheaper/faster. Faster being the key word.

1st Gen D50 weren't very popular and got hit with the "Obsolete" tag fast. Very cool niche trucks, but working on them now is hard. Interior 3x so.

Any standard door card will work for those interior kick panels, measure and cut. Just need to get them covered.

Good luck and post pics!
