I would like to know who makes this exact "front" wheel? American Racing and E-T Mag make something similar but not exactly like this...
The chassis in the pictures belongs to @alfin32, so he would be able to tell you more about the wheels in question.
These are the wheels you are looking for - they come with either a Ford 4 1/2 or Chevy 4 3/4 bolt circle.
These Trigo wheels are PIN DRIVE... meaning they use (1) large spinner to hold the wheel on like an old Jaguar. I need wheels that use 5 lug nuts to hold the wheel on. So-Cal also sells the pin drive by Trigo.
Those in the Trigo pics look to have what i call a "soft" outer lip. I think some early magnesium wheels had soft lips? I know you say PS Engineering is two piece but those on the chassis in your lead-in look just like my PS on my Sedan Delivery.....................These are about 24 years old now...........
Trigo, just drilled and finish machined to be a bolt on rather than a pin drive. Either done by Trigo as an option, or by a a local machine shop, or the owner himself if he has the equipment and skills. Your just drilling clear through one of the already there pin drive bolt patterns, and then spot facing the holes from the front side for lug/wrench clearance, depth, and washer contact area.
