I'm not sure yet if this will even work. Gordon found me some dimensions that I'm going to compare side-by-side to those of the Hoopty as it sits now.
If I can make this work, it'll be really neat.
The plan, subject to lots and lots of revisions, will be to weld reinforcement into the coupe body before dismounting it from the chassis, so it doesn't warp or flex too much as it comes off. The bottom of the car, along with the interior and the running gear, will also have to be supported with a jig of some kind, so that'll probably get done at the same time. I have no idea how that's going to work, but it's probably got to be done.
Then, assuming the body clears the Hoopty's dimensions, we're going to hang it from the rafters in a pulley system and slowly lower it onto the chassis. When it's at a manageable height, we'll tack some supports to the chassis and keep going until we have at least eight points of contact to put Dzus fasteners in on, fabricate feet for the fasteners, make them functional and finish weld the outriggers so they support the hollow shell over top of the car.
Once the shell's on, we'll be welding gusset plates vertically in the nose and tail to meet the existing hinge bolts, and then we'll be able to remove the body and set about making all the welds solid.
Badda-Bing. Off to the sand-blaster and then to the paint and powder guys.
Hopefully, between now and then, I'll find a nose section without all the front suspension components, fuel tank and so on. All I'm gonna need is a skin. Shouldn't cost much.
TC, thanks for continuing the search. Gordon, thanks for the info. I'll be taking photos as soon as I can get to the shop during business hours.
