Possible To Convert Back?? (Roll-Up Windows)

[SierraMtns]

Good Evening Guys,

I want to convert the windows back to roll-up. The previous owner had a shop convert the windows to electric. I am not sure about the details of the kit that was used. The only info I know is which local glass shop cut the glass.

So before I jump into ripping all the wiring out. I wanted to ask the great minds on here a couple questions.

1. Is it possible to keep the 1 piece window and have it be roll up?

2. Will the stock OEM roll-up mechanism work?

Pictures.




Thanks
