I just bought a 1992 prelude si. the owner before had a pully prob that he didnt take care of and it ate every tooth off the crank shaft, including the key stock. How hard will it be to put a new crank shaft in, and about how much will it cost me. the car only cost me 650.00 everything else is in great shape. i just want it on the road as soon as possible. right now i am driving a 1995 accord ex auto. any and all help would be nice. thanx
