Power Windows
Sorry about the delay... didn't realize I had a post pending...
It's actually a straightforward swap... you pop the panels, and take the manual regulators off, and install the electric ones in their place. Different bolt holes, but no drilling or adapting of any kind. Just make sure you get a good set, and you clean and lube 'em up well before installing them.
Only detail is... you have a couple holes you have to plug up, and you need to get a couple of switch panels. I would recommend some aftermarket ones, as the stock ones are problem prone, as you will find in a number of posts. I got some cheap chinese ones, that are working OK so far. You can place these over the holes, if you don't want to put a plug in or re-upholster.
