That's also the one I bought. Took me forever to figure out how to bolt up the block to it though... my first time.
I ended up bolting directly to the stand plate (removed from the stand), using the tubes of the four swivel arms as spacers. Then I hoisted up the block with the mounted plate and stabbed the plate support into the stand. I just couldn't find a combination to use the swivel arms!
What am I missing with the use of that tool? It just didn't seem as universal as I would have imagined and I always seem to make simple things difficult.
