There are parts out there. Just need to find a source that is still in business. They were used in a lot of diesel trucks, too.

Don't forget that there is a LOT more than just a master cylinder needed to connect one of these. (master cylinder, bracketry, hoses to the power steeringm

Also, the next thread you post with "Mr. Tip Top" as the subject will result in your being banned. You haven't seemed to learn yet.
