While not as finely made (and illustrated!) as PT81Jan's bearing tool, this is my 10 minute MoPar bolt circle gauge / locating pin template. (let's call it a "proof of concept" model). It's a (very) quickly (crudely?) cut disk of artist's "foam core" board sized to fit flat against the bold circle of a typical wheel. Using a 14 inch steel wheel from a '67 Coronet as a template, I glued short pieces of wood dowel to the disk, and gave them a couple turns of duct tape to snug them up into the wheel's bolt holes. I then traced the locator pin holes from the Dodge wheel and carefully marked the centers with a 1/16" pilot hole. I use this this to quickly verify the bolt circle of wheels of unknown lineage, and in the case of the Ford 15" steelies I put on the rear of my P12, it was used to drill pilot holes for the locator pins, nicely matching the 14" Coronet wheels on the front. Eventually I may duplicate this using more robust materials (1/4 inch Masonite, maybe) but for now it's fitting the bill.
