A little more progress, as we now have the floor fitted.
We had to do a lot of repair work to the rockers/inner rockers, as someone had decided to drive a large punch through the bottoms of the rockers for drainage or something.
We also felt the best way to get at the holes and jack damage on the outer rocker, was to remove the inner rocker.
After a lot of cleaning, welding and grinding, as well as some primer sealer to the inner rocker, and POR 15 applied to the inside of the outer rocker, we were ready to affix the inner rockers to the new floor pan.
I originally was going to use a floor out of another car, but we realized the pan was slightly tweaked from a wreck the donor car had, and there was some small rust holes starting in the driver's footwell, that grew as I tried to weld them. With that, decided to use a good repo pan.
We'll have to remove the bucket seat brackets off it, and later put in a good used bench seat floor hump.
