BODY GAP ADVICE

Keep in mind that you need to set the gaps with the weight on the wheels (or at least at the axle points) and the doors with the weight of everything that mounts in and on them.
The car is a shell right now sitting on all 4 wheels. So, in order to do this right, I need to assemble the car, set the gaps and disassemble to send it out for paint? I didn't want to mess with the gaps too much with fresh paint in case I need to cut and weld to get them right.
