Update:
So I have the kit installed now, truck back together. The data provided by replies above was extremely helpful. But here's my problem, I took it for a test drive and all seemed great. Didn't get over 20mph or so and when I back off the throttle I get a rotational tapping/clunking from the u-joint end of the enclosed driveline. I reassembled painstakingly and with many pictures and notes. What in the world am I missing? It accelerates with no noises. Only on deceleration while in gear. I took it all apart and reinspected but found nothing obvious.
Anybody have some ideas?
