I recommend taking the driveshaft out yourself, and then taking it to a shop to have them swapped out. Shouldn't cost much, and should only take them 10 minutes. Some driveshafts are very balance sensitive, and you can land up needing to get the whole damn thing balanced if you get frustrated and damage it.
Normally i'd say just buy an aluminum driveshaft, but in the last few years the price has went up like a $100.
