I had a stock 98 XLT Reg. Cab that I installed SPAL power windows, and Autoloc Power locks / Remote entry, with a Stellar (Autoloc Company) Remote start. I am definately an Autoloc Fan, I would have purchased their windows if I had done more research, I think. Everything was pretty easy to install, about 1 day or so (maybe 7-9 hours) but I was doing some different things as well, (powerwashing the carpet, painting the interior pieces, etc) and it was my first time really playing with the truck's electronics.
It was definately worth doing it myself, though, because I could add features that I liked, ie installing the windows with a constant 12v, so I could put the windows up/down with out having to start the truck. After all, how many times do you turn off your car and forget to roll up the windows, just to have to put the key back in to put them up.
I also ran the switches under the carpet and through the armrest, so the switches were mounted on the front of the armrest, at my fingertips. Pics can be seen here
The pics don't show it, but before I sold it, I inserted the black plastic cap over the hole where the window crank used to be and painted it white to match the interior.
If I can be of any help, let me know. Go autoloc, and look on eBay for a dealer.
