I need to do this as well. For the last three years I've had to go out and wiggle my battery cables to get it to fire from time to time. I bought the military cable ends and heavy wire and crimper and lugs two years ago and have yet to fix it.
Factory radiator from @Onur. I think this was the first part that I bought for this truck over two years ago. New radiator hoses and clamps. The 56 mm clamp goes on the water pump and the 51 mm clamp goes on the lower radiator.
