Power Steering Hydraulic Cylinder Available?

[jd68p]

Hey guys. Longtime follower.

I recently acquired a 72 GMC 5500 tilt cab. Working on a few things - one is the power steering cylinder which leaks like crazy.

I got a quote from a local hydraulics shop for rebuilding it - they want $$$, so I thought I might be able to find a used one in better shape. I can find ones for the smaller trucks and cars, but I've searched for the larger ones to no avail.

Anyone have an extra good power steering cylinder/slave cylinder from a C-50/C-60? Or know a source for one?

Thanks. Joe.
