Product review (4 stars): So this kit was a perfect fit for my 10 year old washer and dryer
So this kit was a perfect fit for my 10 year old washer and dryer.  It made for a simple conversion to a full size stacking set. Holes were pre-drilled in the washer and everything fit fine. It looks good when done, and we ahve had no issues wit vibration or movement.

The only difficult is that the front piece is secured with double sided foam tape which is a bit of a challenge to get correctly located once the sticky side is exposed.

 I'd suggest getting a grease pencil or washable marker and fitting the units together without the sticky tape, then mark the location with the grease pencil, unstack them, and tape the front piece into place using the marks before restacking hte units.
