I finally set aside some time to replace my rusted out floor pans on my '65. I removed the seat, floormat, and door on the driver's side. The previous owner had a pop-riveted patch, bondoed to the floor as well as a lot of gooey stuff daubed all over the place. Anyway, I got all that stuff removed and realized that I'll need to replace just about everything. I removed the rocker panel first, hoping that there would be something left of the lower door jamb...but there isn't and the flange that has the three holes to hold the fender on are long gone. There is nothing there to line up with, or to get a reference point from. My plan is to remove and replace the lower door hinge jamb first, then replace the lower kick panel piece, then weld in the floor brace and floor pan. My question is how to locate the first piece...the lower door jamb. Any help would be appreciated from someone who has done this before. I am thinking that the lower door jamb replacement has a step on it where the rocker panel welds on and that would be the starting point. Any ideas? Thanks in advance for your help. Jim
