tomslik & Phil, I never really looked that close at the mounting flange to mounting flange width. I pulled a tape on the chassis and figured to narrow the 72 Chevy cross member by 1-7/8", which would allow me to direct bolt to my OEM chassis. In your travels would this still be wide? I have seen this setup without narrowing and agree it is to wide (even with inside of fender). I figured with the correct wheel offset it would be about perfect. Thanks for the feedback.
