Kenworth w900b window motor replacement

[Precisionw900]

I needed a window motor for my w900b and they only offer it as the complete regulator assembly to the tune of $450!!!!and no cross references for the factory part numbers. Damn dealers are crazy. So after a lot of searching dimensions and measuring my mounting and sprocket sizes I came up with
a Dorman 742-251 window motor that can be found on eBay or amazon or a dozen other places for about 40$. Perfect fit in case anyone has ran into this figured it would help.
