Well first off I have to say this took about a third of the time I was figuring. I thought tapping the box would be the hard part. From pulling the box until it ws back on the frame was about 1 hour. I wheeled with a guy who has setup/sold hundreds of H A setups and he filled me in on how to do it for more than half of all the kits (what a rip if you ask me). After talking with him, I started hunting for parts and found them all @ one place. I'd say this whole setup with box mods, modding the pump, brackets and all might have been 3 hours, and that's high side. Any questions just post up, I'm an experienced veteran now!
Not sure on shaft diameter, I wnat to say 5/8 or 3/4.
