Made some progress on my initial install today. It involves a lot of triangulation and measuring. But at the end of the day I wound up having to drill the holes a little wider than the machine screws and use a file for some fine tuning to get everything lined up. This first one probably isn't 100% centered but I am learning as I go. If anyone has any suggestions about getting them perfectly centered feel free to chime in. I may just use the grease and eyeball method on the rest of them....
Used some masking tape to be able to mark middle points between the lug holes:
Found the center of the wheel:
Also found the center of the cap by finding the center of the triangle creating by the mounting holes. Then measured from the center of the wheel out and crossed that with the center of the space in between the lugs.
Punched and drilled:
Then after some tweaking on all the holes to get everything lined up, finally installed:
They are a touch off center but this was my first one. Once again, open to suggestions for how to get them exactly centered.
I am not done painting up the center caps yet but wanted to mock one up.
Also, the center bore on these US wheel steelies is larger than the OEM wagon wheels. So there is actually a touch of space around the center cap and the mounting surface. They mount flush to the wheel, but there are some openings since the center bore is larger. But you really have to look to see them.
