Same here ,I use them for quick mild steel jobs .As Joe said ,the S&W kit is usually fairly close as far as notching and fit .
The hoop and rear bars usually are damn close ,the side bars I usually tweak for extra shoulder and armrest clearance .
Because the tubes are machine notched by a plasma machine you still need to do some cleanup grinding on the tube for a clean and perfect fit.
Personally ,I would not build an A body Mopar without a full cage with bars thru the firewall .They are just too flimsy ,search back thru some of the threads regarding crashes with them.
