I just did a conversion from manual windows to power windows, I didn't do
the locks since I shaved the handles, so there is no need to have power
locks. I did the conversion using the stock power regulators from
another s-series truck, some people just buy an aftermarket kit like
spal or autoloc , but I didn't want the manual crank piece sticking out
of my door panel (aftermarket kits come with a cover), and I think that
theres less things to go wrong with the the stock regulators than the
aftermarket kits, I took some pictures, I hope they are use full for
you if you are going to do the same conversion.
