I just recently replaced 2 timing belts, 2 water pumps 2 thermostats and 5 acc. belts on both my 3.4 4R's. Everything was working when I removed them....not sure of the mileage on anything as I bought both trucks used....the old ones are available to a good home! I figure they would make good trail spares. They are yours for the cost of shipping.
Contact me at psdtoddmxz@yahoo.com if you want them
