Most dealers dont like to or can afford to tie up lifts, leaving it on a lift for 3 weeks waiting for a piece of sheet metal doesnt add up either.
Good points except due to setback being measured on the front caster swing, setback for the rear won't be measured.Take your car to a good tire shop and get a 4 wheel alignment. A good shop will have a printer hooked up to their alignment machine and can give you a copy of your wheel alignment specs. A laser alignment will tell you exactly where your wheels are and if they are in spec. This should be done on any car that has been in wreck like this. Most body shops don't pay the money to verify if their work is correct. It will tell you if your wheels are to far forward or back as well as camber, caster and toe specs.
