cab too hot

4020 aftermarket steel cab used to have a powered ventilation fan or blower. No I.D markings as to who made the cab other than it is from the late 60's.
The windows are very heavy glass and are hinged at the top. They do not have latches as they are bolted shut with no means of support is swung outward.
There is a 4 1/4" hole in the roof for a fan/blower I think. I do not want a Solar powered weatherproof fan. I'd like a 12 VDC fan on a switch.
Is there a drop in weatherproof fan you may know of?
The windows could be on prop-open latches but they would have to be heavy enough to support the glass windows with out twisting them.

Decent cabs for 4020's are cheap. I would get rid of that cab and get a yeararound or a Hiniker cab with doors and windows that can be opened. Tom
 
Originally, it would have had a simple (non-weatherproof) squirrel cage fan hanging inside the cab with with a filter with a rain-proof "cap" on it on top of the cab.

Window latches/props probably looked like #10, (below) or were "scissors" similar to the door prop shown, #1.
