Has anyone out there restored a butterscotch interior 240z? Do they make new plastic panels in this color or will I need to purchase the black ones and have them painted? Thanks.

I think you'll have to dye them yourself. I've used SEM brand interior paint on similar hard plastic panels on other vehicles with excellent results. Just make certain that you also get the SEM Surface Prep and follow the instructions exactly.

That is pretty much the answer, unfortunately. You could try Classic Datsun http://www.classicdatsun.com/ but be wary that certain interior plastic panels apply to certain years if you are looking for correctness.
