since the build shop is 2 hrs away, and the pro shop that did the set up in the first place let it go like this (wrong, so you don't really want them doing it again and again), I would say talk to the hotrod shop that did the build (and sublet the driveshaft) and see if they will simply cover the cost of getting it fixed at a local shop. it's your time and gas money he is playing with, as well as his name in the business, so he should jump on that like a fat kid on a burger. it costs him cash, yes, but also stops a come back to him if it has further issues with that item of the build. he may be able to pay for the job directly/remotely but make sure you get a copy of the invoice in case there are further problems.
