Drive on lift

Are you building the FCs or is he? You can do a lot of prep yourself before you bring it to him and save him a lot of time and you $. You could even do all the finish welding at home...if your a welder. Just nice to have the chassis loaded/wheels on the rack when you start welding them in.
FYI Have all you plumbing and parking brake cables sorted out before he starts welding. It costs twice as much to un-weld.
