Pro Performance gave you some great advice if this is what you really want to do. My question is do you really want those rims on that truck? It seems that it will take a lot of effort to get those rims to fit and they really don't go with the style of truck your building. Since your not going with a low profile tire, we can assume that improved handling isn't your objective. It would seem more logical to sell the Vette wheels and buy some that are a direct fit, AND go with the theme of your build.
I'm not trying to offend you, just offering an outside perspective since I really dig your project.
