I would like to install the 4 post 30K lift, but the floor has water pipes for heat under the slab. We don't know where they are, and the posts have to have a pier under them. The floor has 8" piers under the slab, cannot remember where they are. I thought of fastening 4' x 4' plates 1in thick to the floor and then fasten the posts to them. The floor is reinforced with reinforcing steel. I need to find the reinforcing in the floor and try to miss the bars with the plate anchors.

Once I get down I have to either make do with what I have or haul all 300 lbs of myself up and get what I need then when I get within a foot of the floor, I usually just try to fall on something soft!!!!!! I have seriously been looking at this creeper made for aircraft. https://ezcreeper.com/ I just wish it was available with an electric pump. I have been looking for a drill powered hydraulic pump to adapt to this creeper.

But sorry, I reject the notion that bringing the wrong wrench is a blood-pressure-raising event, and I stand fast by my comment. This simply isn't an argument against the metric system. Seriously, just bring several wrenches...

Having the wrong wrench when I get under there is not a happy event. Should I give up DIY wrenching? Not a chance as long as my body is still warm. If I didn’t keep trying to do this stuff I would have been 6’ under a long time ago,
