You can get all the guts from a power equipped s10/15 or come up on a pair of power doors which is much easier on the instal process.
Run the factory harness from the doors to the cab then use New relays. add a new pin kit to both doors
My 2003 S10 is manual locks manual windows and chances are I will never have to worry about either of them failing, while switching to electric it can be hit and miss sometimes they last forever and often times they go out after so long which eventually since these trucks are aging and parts in general are in shortage due to Covid if you plan to keep it long term it could become a problem, just look at the square body S10's on how parts are becoming hard to get for them.
Very easy to just reach over in these trucks and unlock the other door unless you are disabled which in that case I would understand.
If you go the route all I can say is buy spare parts while you can.
Now I can remotely open each window up and down separately, open each door popper separately, and still have many other channels available for other remotely operated things.
To me, the late model door panels look better than the early ones.
And also, I had a custom run of inner billet door handle pocket trim reproduced. I have about 20 kits (doors) left. These are reproduced straight off of real 1990s billet pieces. I wanted them, several people wanted them, so I had 50 trucks worth made.
