Ok, I have some progress pics to post.
While the interior pieces were out, I gave them a nice good cleaning. They were filthy.
A-Pillar Interior Pieces, where the Seatbelts go through.
Before.
After.
Next, I ditched the 91 stock Side Duct vents, and made some custom 02 Style grilles. I found a steel wholesale place nearby, and was able to use the mesh in the valance as a reference. Luckily, I was able to find a spot on match, to the OEM 02 Mesh. These grilles are over 400 a piece from the dealer! So I saved big time...
Stock 91 inserts, picture reference. (picture taken, before paint and bodywork)
02 Style Mesh Side Duct Inserts, I fabricated and powdercoated.
Cleaned behind the side ducts, one last time, before installing.
Installed. New OEM Clips, and factory hardware all torqued down.
