Hi, hornbrod,
You mentioned that the activation rod on the rear proportioning valve is different on 2WDs and 4WDs and also different on different years. Do you happen to know the lengths of the different rods and their applications? We are making a lift kit for the Comanches, and that information would be very helpful.
We have a 2WD, 1989 Sport Truck that we tested our 3 inch and 4-1/2 inch kits on, and we just made longer rods for ours.
Thanks,
