Wheel Vintiques Steel Wheels ?s

For just a couple of extra bucks, WV will put the spider almost anywhere you want it; so you can specify the backspace.
So then I would maybe go 7.5s on the front with 235s and 8.5s on the rear with the biggest tires you can stuff in there which IIRC is 255s, but not sure.
Putting fat tires on skinny rims, while possible, does nothing for handling, and can prematurely wear the tires out. Get it right with the pressures dialed in and the tires cam last ......... a really long time.
