Replaced the upper and lower driver's hinge pins and welded in thicker sheet metal behind striker pin nut capture plate "before" I rehung "Frankin-quarter" (long story). So welding and fiddling to get everything just right was much easier. New pins as originals were shot, probably ½ material left, wanted door to be gapped correctly at rocker and jamb to help align Frankie, and since the jamb was cracked at latch pin it was prime time.
On "Franken-quarter"; I knew there was prior repair at driver's rear wheel arch and as I was removing paint I revealed what I figured to be a late 70's fix... Apparantly the car took a hit just forward and on the wheel arch. Whoever did the repair, with technology available to them at the time, took a spanking new from Chrysler quarter and pieced the damaged section in, they also installed a new from Chrysler door skin, both brazed in/on. Now they attempted to "butt braze" the quarter section in and did a not too bad job everywhere except where they cut old quarter front and sized the new piece to meet right, vertically up, from wheel house to about 2" above the body line. They overlapped, by like 4", the horizontal at the c pillar but didn't overlap anything at the vertical from the wheel arch. Yep, the heat from attempting to butt braze warped both old and new panels. They ended up pop riveting a 3" wide piece of metal behind so the butt could be loaded with brazing rod. Then mudded it up. So, after flattening what I could (front section off) of both pieces and trimming of what was beyond working with, I had to piece in a 2' wide vertical making body lines and wheel arch bends. Then lapping all the pieces (thank god for pnumatic combo hole punch/flange tool) and cleco-ing and screwing them where they needed to be for plug welding, not real good with mig to even attempt butt welds yet. On top of that (3 pieces now) I had to bang the hell out of the inner and outer wheel houses to get them right and then a small metal repair on the once new old front quarter (4 now) and then I was able to fit up the trunk vertical (not part of Frankie) and fit in the lower quarter rust repair panel. So for those who are counting, or not, that's 6 pieces welded in and pretty darn square, body lines and wheel arch all metal and welded. I'll need maybe less than an ⅛ of filler, not saying it won't be wide and tall, to get it ready for primer. Hence "Frankin-quarter". Of course I still have rust repair on the lower rear of passenger quarter and trunk vertical to do yet, then the "tub fun" can begin...
In hindsight it would have been easier to install new quarter and so forth, but I had more time than funds at the time. Besides that wouldn't have been as much fun...
