Kubota cab

Here's probably the easiest way to find something that is very near the exact size you need and is relatively cheap:

Go to Summit Racing's website (because they have a large selection) and search for "fluid coolers" (transmission, oil, etc.)

Once you have the listing up for fluid coolers you'll be able to refine it by overall size (L x W x D), size of fittings, etc. Then sort the list by Price, low to high. Skip the coolers with fans (too pricey, and the fans will be too powerful .... and noisy)

Pickup a large muffin fan used for computers - I just picked some up ultra quiet Antec ones from ProVantage for around $10 or $15 I think.

I live in northwestern PA and I have had a home built cab on my tractor for about 15 years and have never needed a heater in it to keep the windows clear. If you blow snow into the wind and it blows back on you it will fog up but the heat of the transmission will take the chill off inside the cab. Most of the time I don't even wear gloves in the cab. The cab is not insulated and is made of plexy-glass except for the front and rear windows, they are safety glass because I have wippers and they will ruin plexy glass or lexan. That being said I would NOT use plexy-glass or lexan for the front or rear windows it scratches too easy use safety glass you will be much happier! I got mine from an auto salvage yard from a mini bus, and built the cab arround them. but you can buy it from a glass shop cut to whatever size you want and also get the rubber to install it if you want. Mine had an aluminum frame.
