Used two post

[BBCfan]

I looked at a used two post lift to give my old body a break. Can't find anywhere to buy the floor mounting hardware. I'm certain they'll destroy the floor bolts when it is removed. Where might I buy this hardware at?

Who's the manufacturer? Maybe check with them, might sell a mounting kit.

You really want a footer under those posts.
They usually are 3/4” diameter concrete anchors, the length would be for the thickness of the concrete. Big box stores may have those, not sure.

I checked with the local dealer and got a no go. Northwest PA is so ridiculous at getting anyone to do anything that I generally don't bother with dealers and that is why. They didn't even want to setup the main posts and leave the upper half to me....lotta ******* in my area! I don't plan on anything heavier than 4500 lbs on a 7000# Rotary lift. I think my barn is 4"-5" thick where I plan on setting it up. I will drill a couple of holes to verify that. I will also rig up some type of a jackstand system in case something were to go wrong I'll have a extra couple seconds to react. Don't like being under heavy things at all.

If I didn't know for sure what my floor was,and by that I mean reinforced,or not. I would cut 2 sections out and pour slabs with j bolts to mount it. Minimum I'd throw down steel plates if I wasn't going to pour mounting pads. The plates will spread the load over a greater area and allow more mounting holes to be drilled across a larger area.

Yeah, need deep enough and wide enough footings and sufficient mounting bolts, otherwise it's just an accident waiting to happen. 4 to 5 inches of non-reinforced slab will fail sooner than later and you will potentially be under the vehicle when it does. Or a family member or pet. It's worth the effort to install it with sound engineering in mind. Safety first!

What @Ricko1966 said.
If you are just putting it on a typical garage slab, you won’t have enough depth to get full embedment on the concrete anchors.
Anchor posts to substantial steel foot plates. Anchor plates to floor over a larger surface area.
However it sounds like you maybe should get someone else to install it.
