Only thing my interior needed was matching OEM-style floor mats. I got these from Classic Parts. Not cheap, but heavy-duty rubber, color-matching, bow-tie floor mats. They are one size fits all, so you have to take some exact measurements of what you want, and then go to work with a razor knife and straightedge, with a little tin snips cutting for the round corners. Makes a big difference in pulling the interior together.

The color on the driver side here looks a little pinker than in person. Cameras have trouble with rendering red. The passenger side one is closer to actual.
