Tubbing the Valiant

The metal bashing continues. Heading front to rear but, I do have a question for the experts out there. I was thining to place the shell on jack stands to load or unload the shell as if it was sitting on wheels before I bond the sheet metal & tubs to the inside of the rear quarters. My Bud says to get the drive line back into the car ans set it on the wheels first. I don't want to go through all that work to only remove it later to paint & install the plumbing. It flexs on the rotissarie a bit but all is square on the jack stands. Any advice will be greatly appreciated.
