I bought one of those harbor freight jack tables. I love it for 911 drops. It easily holds all the weight of the motor and trans, and is really stable. Once out, I can roll it around the shop, and raise it up to meet my engine stand, or workbench.
I would highly recommend it, I have found tons of other uses for it.
I got lucky, when I went to purchase mine, they only had one left, and it did not work. Store manager offered it to me for $100.00 Got it home, bled it and walla! I've been using it for years now with no issue .
I use it as a work bench, and it also makes unloading heavy items from my truck a breeze.
The only problem I have is that the handle hits the rear bumper of a 911 about 3 inches before the load is centered perfectly on the table. I just remove the handle when pulling 911 motors. It comes out in 10 seconds with 2 pins .
