upgraded GM which part # for one touch windows

[cobb535]

I have a 1989 535i and would like to swap in an E32 general module to give me one touch down windows. I have seen info on this board before but can't seem to find it. Did all E32's come with one touch windows? If so then any general module from one should work for me. If it was year specific a year range or part number would help me.
On another note I drove a 540i 6 speed today. Compared to my 535i automatic the difference was night and day. I GOTTA GET ONE OFTHOSE !!!!!

i have the 540i, just no 6-speed. Hell id be happy with a 5-speed swap. Well, maybe next spring hopefully. I atleast have the driveshaft.
