Need rear wheel backspacing suggestions for 65 valiant with mini tubs and inboard spring kit

Define “break the bank” for us too.

My Billet Specialties Street Lites were $1200 per pair. You chose width and backspacing.

I also looked at WheelSmith to build custom aluminum rims so I could keep my dog dish caps and they were through the roof…$3000+

WheelSmith does have less expensive rims if you’re okay with steel smoothies and a plain cap
