Those look like the wheels sold in the DC book. I dont think they are a 4'' bolt circle. The 4'' and 100 mm are so close, if he used a ruler of mesuring tape, hed think it was 4''. Id bet money those are 4 on 100 FWD wheels.
Joey Shelby was a sourch of aftermarket wheels back in the late 70s and early 80s. I'd bet those are for a Pinto, or Vega. I know the Vegas (H body) and the HS body (Monza,Sunbird,Starfire,Skyhawk) had 4x4" pattern. But the offset looks like a FWD application. I have heard of people using 4x4" on 4x100mm. but I NEVER would. The custom wheels I had on my 1980 Sunbird had oval offset washers and slotted holes in the rim, so they would work with 100mm or 4". What is weird is that they are standard patterened wheels, but he has metric lugnuts. Back then I would assume that anything US would have had standard studs. -----------------------REMOVE-FOOTER-WHEN-REPLYING---------------------------- Questions?
