Tires and rims

Hey

My 68 Barracuda Fastback has factory 8 3/4 axle which has 4" bolt circle and the front has disk brake conversion with 4.5" bolt circle. Has anyone found rims without spacers to get the tires as big as I can to fit underneath - keeping the car factory ( other than the brakes )

I would like to keep existing a axles and just get sweet looking rims with new rubbers.

Thanks.
