Kodiakz,
I'll have to check with the shop that did the install of the radiator for the size. I know it holds 3 extra gallons and I believe was 2 inches thicker then the stock unit. I know the radiator would not work with the H2's stock clutch fan in place it barley fits with the electric fans.
I would think that any quality radiator shop should be able to get one for you or have one made. It is made out of the same material as the stock unit it's just deeper/thicker. I can tell you although just my personal opinion backed with some research and personal observations, to stay away from aluminum radiators.
I'm still considering a deeper trans pan:

I still need to get a hold of them to verify if the pan they are offering will fit the model of trans in the H2. The "Hydra-Matic 4L65-E" is not listed as a trans that their pan will fit on.
I also looking at one or two additional trans coolers to be placed in the front grill next to the inner-cooler for the s/c but the available space is only 8x8.5 so I'm not certain I can find anything to fit that space, then there is the further reduced air flow to consider by adding anything to the front grill area.
Removing the existing trans cooler and replacing it with something larger seams like the most do-able option but I'm still researching.
