I'll talk with a member who is trying to do the rocker moldings.
A couple of people have asked about the headlight rings, but don't know if they got them or not.
Another almost unobtanium part is the big plastic '69 inner grille surrounds. They are re-popped, but most people I've read said they fit poorly. I found a complete set of NOS grilles and drove from VA to CT to get them and some other NOS or really good used parts. Didn't trust any shipping company on those. Lot of members have to restore what they have, sometimes collecting pieces to put together, so they are asked about a lot.
Maybe you can start a thread poll after you and your buddy look at those parts or other suggestions you might get. IDK how much, but I'm sure there is some design and start-up costs for each part. If you don't have enough commitment, then it probably won't justify the costs.
I think a lot of people would like to see how your console lids look when done. I'm working on dash and console right now and am on the fence about ordering the top plates, so I'd like to see yours.
Good luck,
Dan
