Propshaft and steering fin repair

[Self taught mechanic 0]

Just acquired a 2007 enzo sv216 and the second time out we found a rock in the lovely Susquehanna river messed up the prop and rudder,bent the propshaft about a 64th of an inch and of course scratched the bottom properly and tore the one steering fin out and bent the other one question is where do I find replacement bolts for the fins and can a machine shop straighten the propshaft or are there any repair shops equipped to do that in the Lancaster county pa area ?
