Hi, I am new to this site. I recently purchased a 69 Javelin SST 390 4 speed car. It came with what appears to be factory steel Javelin /AMX wheels in the trunk. I had them mounted on tires, however the front calipers are not allowing the wheels to turn. Are there 14" disc brake wheels that are different than the drum wheels? I did try a spacer I had laying around, and that worked. But now the wheel studs are too short. Does anyone know if I'll have a problem finding the longer stud? Thanks in advance.
