Yes, they are small bolt pattern. I run an OEM A Body 8 3/4 rear and Kelsey-Hayes front disc brakes. They were custom Minilite 15 x 6 for the early A Body cars. Kinda wished I would have gotten 16's for tire selection. I ordered them through Minilite US ( Minilite Wheels US ) I'll check and see if I still have the specs. They did not have caps small enough and they came with a lip that had to be machined out for the front hubs to pass thru. Very nice wheels though. they are centered in the wheel wells as close as you can get. Hub Centric and steel inserts for standard lug nuts.
