Take off wheels!

Any ideas on a factory take off wheel that might work on my 64 nova? I have not ruled out he idea of a mini tub. I like the look of 5 spoke c5 vette wheels. I just want some ideas so I can keep my eyes pealed for them cheap. PICS would help alot. I did find a set of c5 vette this is the link but i dont think they will fit. sale-1050893044@craigslist.org

I could be wrong, but I believe you don't want to use anything wider than 6 inches in the front and 7 inches in the back unless you make some major modifications
