Again, thank you. The lift is together and working! The local Clark dealer here in LA, Cal-Lift, was able to get the right seal kit and all the information about the lift for me. I used thin sheets of plastic to make the cone that protected the seal from the threads on the way in. A little tapping on the bronze guide with a drift got it in far enough to engage the threads on the gland nut. Once the mast was up I could see how those two spinning bolts on the side of the mast work. Still have not seen how the manifold connects on the bottom of the cylinder but it will be much easier to check it out now that the mast can go up.
Celebrating a day without being covered in oil.
