u can grind about an inch or 2 of the floor on both edges and put zinc? rich weld thru primer on it then tack it in then weld the floor in, in inch or so welds til u get it all done to keep from warping (dunno how much u hafta worry about it on a floor but better safe than sorry hehe) and grind it. u can get good seam sealer from a body shop supply for about 4 or 6 bucks here in canada and put that on the welds after theyre in then paint it. at least thats what i woulda done to mine 15 years ago when i had done mine if i knew better hehe. and the door jam i made pieces up and mig'ed them and then ground them flat it woulda been jsut as easy to mig in pieces from another car but i didn't have them. hope that made sense oh make sure u cover any glass that might get weld splatter or grinding sparks on it as well as the dash area i cardboarded it off and was very wary of fire so i kept a garden hose in the garage and a wet rag to put on the welds. but i'm not an expert by far
