This is an easy conversion with a little money and time. Most of the cost will be in the reversing relays and wiring. First thing is to find the regulators you need. Get the right and left regulators, motors and the wiring if you want to use those switches from mid 80's Ford van. I had 20 dollars in the pair. I don't know if anything else will work so if you can't find a van in your local yard print off one of the pictures here and see what you can find. First thing to do is swap the motors on the Ford regulators as they will not fit in the Scout door unless the motors point to the front of the door when installed. Second thing is to remove the door glass in your Scout. Follow the manual and be careful, the regulators are under a lot of tension and can either dent your door or maybe break a finger. I would do one door at a time in order to avoid confusion. I started with the drivers door on my Scout. Once you have the stock regulator below) out compare it with the ford regulator. This should give you a good idea on what you need to do to the ford part.
The first thing you need to do is flatten the Ford regulator out as it has two bends in it. Then measure from the pivot point on the Ford regulator and mark it at 3-3/8's of an inch to match the IH arm. I then cut the Ford regulator off about 3/4's of an inch past were the hole will be and rounded the edges off a little. See the picture below.
I drilled the hole 3/8 of an inch in size. Then sand or file the area smooth. Then cut off the head or the rivet on the stock regulator and use a punch knock it out. You can either use a rivet made for this or make something that will work. I made my own fastener using a Chevy S-10 blazer door pin bushing (bronze) sanded down to just a little thicker than the regulator arm, a nylon washer between the regulator arm and the window track arm and a grade eight bolt with a thread lock nut to bolt it together. I then greased everything on the assembly at the wear points after cleaning out the old grease and dirt.
Here is the finished regulator and window track. This is the driver side. Notice the motor is pointing toward the rear of the door if it were installed, this is wrong as it should point to the front of the door if it were installed this is why you need to swap the motors from side to side.
Now it's time to bolt everything in the door. When installing the motor section to the door, three of the four bolt holes will line up. The fourth one you will have to drill a new hole down lower than the factory hole, about an inch. This is because the gear on the ford regulator is in the way of installing the bolt. I used grade eight bolts (short ones, about a 1/4 inch long) with locking nuts. You can also use rivets if you want but it's better to use bolts if you ever have to replace the motor. Next you will have to make up your reversing relays, two for each side. The hardest thing for me was deciding on were to mount the switches and how to run the wiring from the doors to the body. Refer to the wiring diagram for information on how to wire everything up. I used a separate fuse(30 amp) for each motor and set everything up so the windows will work with the key off.
This is what the finished door looks like in my truck.
