Ridler 695 Wheels for a 72 Chevelle

[crazycarguy22]

Found these wheels while searching across the internet for an affordable alternative to 3 piece custom wheels. Had a couple of questions and was hoping for some answers from some knowledgeable people.

First do any vendors on here sell this wheel and if so at what price? Second, my car (72 Chevelle) is currently running 8" fronts and 10" rears and would like to stick with that, but the wheel is only offered in 18x9.5" is it possible to get an 18x10" wheel from anywhere? Finally, is it possible to buy wheels completely unfinished/raw to custom paint?

Here's my car:
