I have an opportunity to get some tub pieces from a member doing an aqualu tub swap. His tub is from an '78 model with flat floor and my tub is a 12/79 with the raised floor for underfloor fuel tank. My passenger b-pillar and door opening lip is hammered from a likely roll-over event that happened sometime in my rigs past life. I understand the inner and outer rocker pieces are different, but could I use the upper B-pillar and door lip from his '78 to repair my rig? Here are some photos of the damage to my passenger b-pillar and door opening. The replacement rockers for the late model rigs don't go up high enough tor replace the damage on the door opening lip.
