Would the shop let you jack one of the bays to do the work? Im assuming no but if you're cool with your mechanic they usually hook you up unless you go to a formal shop like a dealer. I avoid dealers and go to the shady spots (if for some reason theres something im too lazy/ cant do). I wish I could use a shop for my current swap but im limited to my cold a$$ garage lol. Im sure theyd let me use the bay for a day or two but my car has been down since christmas. Anyways you could always ask and see so you can save some cash.
