I have two, one around 40+yrs old and one 50+ yrs old. The structure is fine, just need to rebuild hydraulics. Kit is like $40 as I recall. I've owned these jacks since new. I have a third one I bought before Sears closed. One 1 1/2, 2 1/2 and 3 tonIt's 30 years old and I really don't trust it at this point. Free to a good home if anyone wants to give it a shot!
