Product review (2 stars): It works, but needed less than half the parts and instructions are wrong
I bought a stacking front load Frigidaire washer/dryer and this kit.  I installed the kit on the washer per instructions and had a large friend help with putting the dryer on top.  The first thing was realizing the legs needed to be fully extended to fit over the rear bracket.  Then it was realizing after getting the feet in the holes in the front bracket that the rear bracket was too far back.  And that there was no way possible to screw through the holes in the front bracket to go into the dryer.

The end result is the two front feet are in holes in the bracket and the dryer will never go anywhere.  The down side is that the rear bracket does nothing and it does not fit as described in the directions.  While I bought all Frigidaire expecting it to work perfectly, it does work and do what is needed, but has useless parts as made.

My suggestion is to first dry fit parts on the floor to figure out what will work or not and just use the needed parts.
