I just installed one manually (without the pics, ha!) and got it to work. I have no pictures, but I can walk you through it textually...
First, the mounting plate: There will be a total of eight holes, four of which are "countersunk" along the outside corners, and four of which are slightly inset but not really deep along the inside corners. Those shallow ones are where the four long screws go in, tighten them down really good (don't overtorque them or you might strip the aluminum). These will eventually be holding down your WW block.
The four that are deeply countersunk go with the four little stubby screws that have fat triangular heads. They should sink in almost perfect so that the heads lay flat with the mounting plate. These short stubbies each get a single washer to seperate the mounting block from your mobo, and you then use a single plastic nut to secure them to the backside of the mobo.
So now, you have the mounting plate secured to the board, and you have four big screws pointing up. Set the block onto the screws, and then each screw gets the following in-order: Plastic washer, spring, plastic washer, brass tightening nut. You can forgo that second washer if need-be, but mine came with enough to do this.
At first, run the brass tightening nuts basically until they stop free-spinning. (ie they make contact with that last washer, or the spring if you didn't use the second washer) From here, I tightened alternating opposing corners (upper left + lower right, and then lower right + upper left) two turns at a time until the springs are pretty much fully compressed.
There ya go
