It used to be a readily available backspacing (maybe not in steelies though), since it's exactly what is needed for a stock A-body rear with minitubs and 3" spring relocation! Guess not enough people are building that combo any more...
I'd have to look it up on my Moser's worksheet, but I think my housing is pretty much the A-body width now.
Anyhow I'll check with Wheel Vintiques, thanks.
The website for The Mopar Dude said that they didn't do custom wheel modifications any more... but I just checked and that appears to have been removed. Unless I'm confusing them with another Mopar-somebody?
