Next on the list was to convert the center caps on my American Racing V500 rims to accept the stock PMD cap.
Here is the stock cap.

The backside of the PMD cap. I need to add longer studs.

Centering spacer that fits into the hub of the rim in two spots.This helps keep the cap centered on the face of the rim.

I don't have any pictures but I had to flatten out the dust shield caps to make a little clearancing room.
Spacer on PMD cap.

Final product. Please excuse the smudged up rims.
