Meh,......100 bucks is all it cost me to put a "No post" lift in my garage..
2 HF boat winches are all it takes to lift the car in the air.... Just the thing when you need to lift something, but don't want the "clutter" of having to deal w/ some post, or apparatus blocking your complete access to the underside of the car.
All it takes is a horizontal span of wood/metal to spread out the lift point load and you'll be doing things you never thought possible before....
Like:
swapping out K members while the engine is still in the car...
lifting 1953 Studebaker bodies off of their frames, so that you can transfer the body over to a rotisserie:
Then putting it back on the frame, when you decide that street rods are a pain in the ass and sell the car to a guy in Texas...
(anybody recognize the engine?.....where have we seen that thing before?)
Nothing will make your life simpler....Experience the raw terror as you wonder how much additional weight your floor joists can support before you pull either the living room or the guest bedroom floor down on top of your head, while an undetermined weight of an all steel body shell hangs in the air so you can roll the chassis back under the thing.....
You don't need no stinkin 2 or 4 post lift,......All you need are bigger balls and a Harbor freight..
