17x8 245/45/17 on all four with 4.5bs?

I have a 71 dart with factory small bolt pattern disc brakes and a 8.75 factory rear. I want to mount some showwheels streeters on my car. i am having a hard time finding out if those combo will work. I know I have seen it on the rear with no problems on several cars. Anybody on the front? Would I be better off with 17x7 4.25 bs? Should I run a smaller tire up front? Anybody not happy with their sbp showwheels?
