I need this. My back isn't what it used to be, so when it's time to fiddle with the undercarriage, I start thinking wistfully about lifts or pits. It'd also make it easier to hang off the end of the breaker bar for those monster-torque suspension fasteners. Exhaust work? No more lying on your back, rust crispies falling into your mouth, embers from that bolt you're torching out ending up who knows where. Of course, it's always a plus to make sure there are no fluids in the car, or they'll remind you of their presence once you get the car on its side.
Eastwood's catalog is chock-full of tools that look awesome, and yet, I have no idea how to use them. Their Tilt-A-Car unit is pretty self-evident. It attaches with the lugs and one side has a radius. You pop your 3/8" driver drill on the lift screw, and it's bottoms up. This unit would have made repairing the rust-tastic rockers and rear quarters on my Volvo 245 a cinch. It's about half the price of a lift – not counting the installation cost, and it seems more useful on a fully assembled car than a rotisserie is.
Thanks for the tip, Keith!
