Thanks for the comments.
I got the wiper assembly pretty much whipped, took a little bit of fabbing but not really too bad to get everything to sit and work together. Only thing left to figure out is electrical. On this particular motor uses a very short ground pulse to tell the wiper module where park position is. Problem I am running into is that I cant use that pulse to trigger a relay because it is too short, the motor coasts past it and kicks it back off. I am trying to use the pulse to break the park power contact in the relay, thereby stopping the motor at the park position. I think I may have to open the gearbox and see what I can do about making the park contact a bit longer to compensate for the wiper train coasting action. I am sure with the wipers rubbing across the glass there wont be too much coasting, but I would rather make things work like butter in mock up and not rely on hopes and prayers.
Started modding and fitting up the heater/AC box from the donor truck (same 97 Ram). It is quite bulky but I think it is going to fit under the dash how I want and not be terribly obtrusive. I am going to lose about half of the glove box space, really no way around it without sacrificing foot space (which would not look right anyway). I have already decided that AC is a must in the truck so there really isnt much option other than to make it fit and work. I had to cut almost a foot out of the ducting/flow direction housing. I already decided I do not want to cut big ol holes in the dash for vents so I chose to go the route of permanent defroster/floor air flow which should serve my needs quite well, I dont like air blasting across my face unless its coming through a window anyway so no need for dash vents.
