Quick question on the hatch area rear wall - in the manual it is riveted in place after the body is installed, however, I would like to still have access to the rear of the car once it is completed and thus want to make the rear wall removable.

My plan is to use rivnuts to the frame, a couple on the side walls and then at the top for fastening the body to the wall.

Am i correct in assuming, that the rear wall is in the same position for all the builds, since it is fastened to the side walls which are fixed in place? And that i can drill and rivnut rear wall without having the body on?

Any better ideas on how to make the rear wall removable?

Thanks,
Nick
