Hey folks need some help please

You can make one pretty easy, you know any guys in the HVAC sheet metal shops?

Have them make a rectangular pan you have measured, to fit the rad, leave fan side alone. Have them give you a big strip for "around the fan" let's say, 2--3" wide or so, and have them "tab" the edges. This will look like teeth. Pull the fan, install the box, mark the center of the pump. Pull it out and cut the hole, perhaps 1/2" or more clearance all around. Install the skirt by bending every other tab flat.

One guy on here mocked one up in ?wood? and made one out of ?fiberglass? I don't remember.
