it appears the body has minimal "side to side" reinforcement such as a full attached floor pan would provide. how are you attaching the body to the chassis, and how is the floor attached ? for my humpback, i am wanting the floor panels to plug weld to the chassis with the cage, and then attach the body to the cage in a perimiter[ think vw floor pan] fashion, with the door jams bolted to several tabs welded to the cage main hoop and dash bar to insure door alignment stays in place.

Eric,
We are both trying to achieve the same goals. That part of the build has complicated things a great deal. I have had some good help with that planing, and we will see how it works out.
The body mounts to four points on the chassis at the front and rear of the rockers, and then at the rear crossmember of the frame. The mounts are solid, but there is room for shims if needed. The doors on this car have adjustable (encapsulated) mounting plates that allow me to move the doors quite a bit, probably a much different arrangement than what you are dealing with?
I am planning on the frame mounts pulling the body back into the same shape as before removal.
The floor pans were fabbed to mount to the tops of the frame rails. Originally we were going to plug weld them, but, instead I am using some stainless steel strips to clamp them to the frame with button head bolts. I may also use a very thin two sided tape to try and reduce vibration. I am fairly sure this car will have more than it's share of rattles!
I think that your plan will work Eric, but my opinion is worth what it costs!
Thanks for the kind words. I am really trying to get this thing together.

Mark
