Finally did something, that's a start...! Arc welded a crack in the frame behind the first running board bracket on the passenger side. Laid it up vertically on it wheels, with the come-along. It sits on the jack stands again. Next on the list is replacing the floorpan. The cab was removed with ropes and a 1/2ton come-along, and a wooden truss in the rafters. It presently sits on a wooden cart with caster wheels, on its back. Looking at doing the buckets/console street rod uograde. i can't see in spending $700 for a floor I can replace myself for a fraction of the cost. I can get a 4x8 sheet of 16guage sheet steel locally for just $45, and some tubes and angles, to make the floor solid enuff to dance on. Will note and remount the rear cab mounts in the proper locations [to be detiremined and noted]. When this is done, will set it up on the frame to find and note the front mounting hole locations, then set it back on the cart, "nose-down" to work some new steel into the rear edges of the pan at the cab walls. Then it will sit upright, and then I can start putting the cab parts back on.
....Still going to be a modern-day Frankenstien to some folks. Beauty IS in the eyes of the creator, but not the beholder.
