1940 Coupe Body to Frame Attachment Points

[Mikey T]

Hello and Merry Christmas! I'm piecing together a very worn and torn 1940 coupe that if I had a brain in my head, I would have cut up and moved on, but this is my baby and its going to live again. I've replaced the lower cowls, floor and sub-rails, rear pan and both rear quarters including drip rails. Basically the roof and firewall was all that was attached. I've lined everything up and the doors all look good but I'm hung up on how the rear quarters attach on the bottom. I know the B pillar is bolted to the sub-rail and front outrigger/support. Then the sub-rail and floor, bolts to the rear outrigger/support. At the end of sub-rail right before the rear axel a bolt goes through the sub-rail into the side of the frame to a caged nut on both sides. This where I'm getting hung up. Should the bolt go through the quarter panel pulling it tight to the sub-rail and frame? Should the quarter panel sheetmetal be welded along the sub-rail? There is another hole and cage nut after the axel centerline, beyond the sub-rail. Should the quarter panel be bolted to the frame at that point? I know the trunk floor ties the rear quarters together and I would guess the rails should be welded to the sub-rail. Whenever I read of someone removing a body from the frame or vendors selling bolt and rubber mounts the four bolts going into the side of the frame in the rear never get mentioned. I'm sure most them disappear from rust but I'm trying to get it right. Any help or guidance would be great. Might be a good question for Kube. Thanks for all the great posts and info.
