Adding a motor to 1974 windows?

[1974911]

Hi,

I have 1974 911 that I'm disassembling and thinking about making various modifications to. At the moment, I'm still in the deconstruction phase, but I'm thinking about adding motors to the windows. I've found articles about replacing or removing existing motors, but can they be added with minimal headache?

If you're interested, I've started to document my progress here. (Bionic Porsche). Some purists will probably be unhappy with the choices I make, but I'm not too concerned. For instance, I'm toying with the idea of making it fully electric, but probably not on this pass.
