I test fitted my new floor pan and it's not quite fitting right. It needs to go back about 3/4" in order for it to touch the welding tabs on the front of the rear sub-frame. In order for that to happen I would need to cut most of the back lip off of the new floor pan. Has anyone encountered this and/or does anyone have any reference measurements. I would have to believe that the only critical thing is the location of the two front sub-frame mounting holes in the floor pan. And yes I did take measurements and photos but cannot for the life of me find them.
