Conv Lift Cylinders

Does anybody know where to buy new seals to repair my top cylinders or am I forced to buy new ones, have mine rebuilt? I'd love to DIY mine?
thanks for any input

Eric,
Find & call a local hydraulic shop in your area. They might be able to fix/rebuild yours?

Or sell you the parts you need to DIY......

Plenty of parts supplies available, such as Grainger -

It's been a while since I looked at the cylinders on my car, but from what I remember one end is crimped to seal the internals. This "crimp" is a full-circle around the perimeter of the cylinder tube. You would need to be able to open up the crimp to access the internals, then have some sort of fixture/press/whatever to re-crimp the end after replacing the internal seals.

For $100 per cylinder, it is probably more cost effective to buy new ones, but if you figure out how to rebuild them let me know. I like DIY rebuild stuff.
