Farmerjoe - 1st off, Welcome to Stovebolt. Since your topic best fits (for now) in the Driveline forum, it's been moved there for further discussion.

BTW - Jerry's advice above is spot on. I would say though that many of the early Big Bolt truck hyrdovacs are extremely rare, including parts. More folks will chime in on the topic, especially if you would let us know what truck you have. wink
