Skitime, what is your twin stick in? I need to find a Transfer case shift for a 05 XL7 case, and thought that I had read yours is in a Gen II rig, so I would be very interested in the production or fabrication of it. Have you had the issues of oil leakage that the other home built conversions are experiencing? Is it the design, or do those boots stop the leakage? Was the Dana 300 conversion that hard? (Using a CAD program raises the level a few notches above those of us that just think it is worth a try.)
Hope that is not too many questions at once, but trying to get as much information as possible before I start my swap to XL7 drive train.
