Go over to the MTF forum,scroll down though some post,check out the set up Steveo did
I agree, Steevo is usually the man at fabbing up stuff. I love his work, and follow his threads often. Check it out, I just went through his power chute thread. It is a nice setup!
As much as I hate that site I did go and try to find the info on the window motor conversion. Did not come up with anything but a couple items referring to Steveo. I have no clue how to navigate that site so try to steer clear of it.
