66 Dart GT wheel quandary

My car came with mis-matched wheels. It's a 1966 Dart GT model with a slant, 9" drums all around. There's one SBP 14" rally with a R78-14 snow tire, one 14 inch steel with a 175R-14 on the back, two 13" on the front with B78-13. One 14 steel spare with a 14"

All the tires are trash but not sure where to go with the wheels, I love the rally wheel look but I have a full set of the original 13" hubcaps. If I get three extra rallys will they work in the front without rubbing, the one back R78-14 on the rally fits quiet nice, and doesn't rub.

Or do I switch to all 13's steel with the caps, and if I do that are the SBP 13's hard to find, and what about finding reasonable 13 inch tires? Are P175/75R13's going to work?

This car will be a weekend driver, no highway, just around town cruiser.

Thanks for opinions.
