i have a set of profile cut frame connectors for my challenger and was wondering if anyone has experience fitting them, the problem im having is they fit really well to the front floor but at the rear section there is a 1/4" clearance through till the rear subframe. my floors are original with no repairs or replaced sections. there is no evidence of crash damage, are the mancini connectors just a poor fit, they look identical to US Cartool connectors and the photo on Mancini's site is the same as 1 on the US Cartool site, urgent help needed as this is holding me up.
thanks dean
