I'm still looking at the repro wheels BIGGERED linked for me. They do custom sizes.

Does anyone know what the factory lug pattern (where they 4.5 on the trucks too?), lug hole and center opening size, and back spacing was on the slotted wheels one could get as an option on a '79 Truck? I don't want to order a special order wheel that I can't return and have it be wrong.

I haven't been able find this information. All I know is they were 15x8.

Thank you.
