Would these work on our cars (70-72 GS)with this bs? 15x7 has 3.75 and 15x9 has 5.0 Probably not enough BS, right? https://www.ebay.com/itm/CPP-US-Mag...-15x9-R-5x4-75-POLISHED-ALUMINUM/382752133272
The stock 15 X 7 Buick wheel has 4 3/8” BS. The 15 X 9 with 5” might work, it could be close on one side or the other.
