parts for 1996 tacoma

Power locks are real easy to add - JC Whitney has a kit with plungers, switches and wiring for about $40. You can tie it into an alarm system too and use a single entry fob. Power windows are more work and more $. JC Whitney has them but suspect not as durable as factory (they drive the widows where the handle would be. With the factory parts you'll need the door panels and probably some of the electric circuitry in the drivers kick panel. I suspect the parts would be costly from a junk yard if you can find them with the right color door panels. p.s. woth factory it is a completely different windwo regulator mechanism.

That looks like the easiest way. Do you think a junk yard would have cheaper power windows?

I doubt that they will let you tear into a perfectly good door -- they would rather sell the entire door complete so doubt they will sell pieces cheaply. I wanted a used side door glass and they wanted $10 more than it was new at a dealer. Do the add on power locks first - its an easy job - just takes a few hours.
