Some time ago I had the rocker channels replaced both sides, however the passenger side rocker channel should of been installed with the one piece door pillar insert when doing the job. My question is can an insert be welded removing kick panel maybe drilling ? holes in rusted but not rotted door pillar to plug weld to new rockers, Hopefully just enough to get to new rocker channel to plug weld , and not hitting frame either, just want to tie everything in? Don't want to take off body again. There seems to be rot on old channel right past door pillar going into front near #1 mount, so I will need to weld cover there so it doesn't get water in there and rot out new rockers .Thanks for any help ,Bob.
