With the curve under on the sides of the 4000 body I'm finding it has to come way apart to get over the cowl hoop. It also doesn't want to go over the frame extensions. I had to start taking pieces off the frame to get the body to fit over. I'm thinking instead of getting away from the original style birdcage I might glass a couple of tubes to the inside of the body below the doors and use these to pin and realign the body like the ally cars. That way I think I can put the back section on from the back and the front on from the front. It's a tough decision to make as to when to permanently attach the body to the frame.
