Got some downtime and get the 14bolt installed. It was bolt in, everything swapped over. Took just about every bit of the gallon of diff juice i bought before it trickled out. I opted to freshen up the parking brake hardware, rotors, brake pads, lug studs, bump stops, even disconnected the brake lines (though you dont have have to even do that) and bleed out the old fluid. Also bought a master bearing kit and installed all new races, bearings, crush sleeve, axle and pinon/yoke seals. Total time from pull in to pull out was about 5 hours with a parts store run and grabbing a bite to eat. Rebuild time was completed prior to the day of install, I spent all day learning how to do that....
All of the tahoe part numbers matched the denali parts that i could find so i just unbolted my 10bolt from the control arms and bolted the 14 bolt back in. I also ended up finding a non-xl denali driveshaft so i have this conversion ujoint ill let go for $20 plus shipping to the next ambitious person who wants to do this. Even blasted and powder coated the new diff cover for the 14 bolt! Only thing i want to caution someone else on is that i do not have a stock exhaust, it dumps before the rear end. So i do not know if stock exhaust clears it or rubs. Also consider replacing your transmission output shaft seal and rear springs top/bottom rubber insulators. One of mine was torn up and i couldn't find it locally so ill have to replace that another time. YMMV!
