My friend just bought some from Diamond Racing Wheel. They'll make them to your spec. (width/backspacing/dia,etc)
Well, if you can still find a pair, you need the good old, bad***, Safety Racing Equip. 2 piece, magnesium wide 5s.
Stockers...albeit after some time on a drill press way back when... These are on a piece of farm equipment in Ohio...
Those look to be buick drums hogged out in the middle, indexed and drilled to use the hub from a 2-piece wide-5 drum. Am I correct?? Any more pics??
I have the Safety-Racing two peice magnesium wheels on my coupe modified...wide fives in the back and six-pin in the front. They're painted gold which was common in the 70's. This Mustang has the same wheels...but still natural magnesium coloring
