this window should be very similar in size to a 33-34 ford. i believe there are a few outfits that have repo kits for this. if i remember correctly, they consist of a regulator and the wood framework needed for installation. or maybe that is two kits ? anyhow, other than the glass size, maybe something like that could be utilized ? i used to have a catalog from "macs auto parts" or something like that from, i think newyork state. i'll see if i can look that up, or you could investigate on line. i think they have a web site. don't know if this was any help or not.
