Tony's Parts sells the black inserts. They are spendy ($85) but are worth it. Mine were still in one piece but would have looked bad against new paint. The ones I got from Tony's look great.
EDIT..........Since this site was updated, every post opens up on the 1st page instead of the most current one. It looks like you already found your scoop inserts. I responded to your last post on the first page.
The car is looking really good!
