Did you check Electric Life for power windows? I bought a factory style scissor lift window kit for my White ACR, but it got stolen before I installed it. Ended up selling it to a customer at work, and it worked very well.
Most aftermarket door lock actuators I've had experience with aren't nearly as reliable as factory ones. Might consider ordering some from a later model GM truck or something. They are similar in style to most aftermarket ones (read: relatively easy to adapt), and last much longer. You could probably grab some linkage parts/pigtails at the junkyard and order new actuators. Just a thought.
I like the way you moved the parking brake to the center too!
Nice to see some progress made...can't wait for paint!
Did you cut the trans crossmember in the above pic, if so, is there a piece that will go back in place when the trans is bolted in? Just curious.
