Are these the the 14X7 magnum wheels used on 1969-70 Chevrolet Super Sports?
If so there is an alternative,albeit a quick fix of sorts.
They have reproduced the acorn lugnuts for these rims,but with a much wider seat area.They look similar to the stock acorn lugnuts used originally.
The new nuts have a seat area so much larger.that they can fill in and seat the widened lug holes.This is noticeable when you come up close to the new lugnut.
Lisbon Chevelle parts,formerly Ted Williams,had boxes of these new design lug nuts for sale at SuperChevy Indy last July.They were designed for this problem you have now.
