Welcome to the group, congrats on the purchase. You guys both have pretty rare cars.
I think that the hardest find will be those wheels and center caps. There are a few guys here that have multiple sets of wheels, and I'm sure you should be able to talk one of them out of a set for your car.
The caps...well, that's another story. I'm hoping to see someone reproduce them, since they are so hard to get ahold of.
