The passenger side is going good so far, I have the floor, cab mount, and rusty firewall sections cut out. The inner rocker pannel was rotten in a few places so I removed it to work on it. Unfortunately all of the 1967-1972 replacement inner rockers that I've found are re packaged 1973-1979 inner rockers which are similar in shape, but far from correct for 1967-1972s. I removed the inner rocker from the 1978 doner cab and cut it up to make patch sections. I cut the patch section out, welded it flush to the bottom of the weather strip channel, then cut the top off, cut a section off the bottom of the top piece and re welded the top back on to match the height of the original weather strip channel. The lower section of the doner rocker was shorter due to the weather strip channel being taller so I cut the bottom off the patch section, cut a larger bottom section from another area and weld it in. This was repeated in a few other places. The front door pillar section is another piece that had to be somewhat fabricated. Once again all of the pillar patch sections I could find were re packaged 73-79 pillars which aren't right either. I happened to have a 73-79 pillar pannel and ended up cutting the inner edge out, massaging it a bit, cutting the lip off, welding on a larger lip section, welded the patch in, rolled the edge to match and cut off the excess. The front of the door pillar also had some rust spots along with the air vent box. The passenger side cab mount bracket was also rotted in the same places as the driver side. Hopefully will be able to get the inner rocker in soon then on to the firewall and floor.
