252 STI doesn't nest inside brackets of power cool W400

Assembling my 252 STI on top of Power Cool W400. I thought the brackets would nest inside each other but they don't. The spacing seems way off. I can move them so they don't interfere with each other but never align them to allow interlocking of any sort. I currently have the cooler mounted to cart but the welder just sitting on top of cooler. I could fabricate a couple of brackets but I'm hoping I'm just missing something in my setup.

thanks,
Matt

Gee,

How about include a couple pics.

Yes, you have to reposition the brackets for the 252.

Interesting... I only needed to remove the rubber feet from the bottom of the power unit to get it to nest on top of the cooler without having to readjust the brackets on either unit.
