I think you need to quantify the price range we're talking about. $300-400 for the front bumper and you probably have solid interest. $800-1000 and I think people will keep searching junkyards.

One question I have is whether your molds will be able to replicate the subtle texture of the OEM cladding. There's an aftermarket company that makes replacement front bumper cladding but it has a different texture, which means it reflects light differently than the other pieces of cladding and is a giveaway that the VX was in an accident. If your replica pieces will look substantially different than the OEM pieces (texture, darkness, fade properties) then I think you'll have very few takers because a lot of us would see it as requiring a whole vehicle purchase to look right. Also will the stock Torx bolts still work with the extra 2mm of thickness? It may also cause the cladding to mount in a marked offset from the actual body which might look strange.
