Was there ever an OE stamped steel wheel that had a 5x4.75 bolt circle and a 3" center hole? Just curious since I converted the bolt circle to the smaller pattern on my '62 Pontiac because I wanted to take advantage of the greater wheel selection that it offers. I have a bunch of A-body steels but they all have a 2.75" center hole and it won't clear the fullsize hub. On the same token, would it be safe to open up the hole of my existing rims to the larger size? Would that compromise the strength of the wheel?
