I got a 12000# 2 post we pulled out of a closed Cadillac dealership. With 12' ceilings, just cleared, we set up between the joists.easy job for me and three buddies. Have to look at the paperwork, as the shop painted all the lifts red, but Bendpak rings a bell. I like the cross brace at top which tie the posts together. Also pulled out a 1200# hydro trans jack, which has way more uses then just trans work. AND four tripod screw jacks. Strongly reccomend those for stability. They also come in real handy doing suspension work . And serve to keep the wheels from free hanging while the cars stored. I use cardboard on the pads also for added underbody finish protection. My old f250 doesn't get that special treatment, lol. You will need , or makes the job way easier, a rotohammer drill motor for the wedge anchors. My 1/2 " Milwaukee worked great. My buddy brought his shim kit over to get the posts perfect. Only talking maybe a few thousandth off,mine was anyway probably not a must. But nice to have if you need them.
