Its a bit harder dealing with the tranny with the t-case still attached,but can be done with some patience and effort..................................................................................................I used two long 3/8" bolts (about 8") with their heads cut off in place of the 2 bell housing bolts on each side of the engine as guide pins to help get the tranny shaft aligned ,while I used my two legs to "kick" the T-case forwards ,to get the main shaft into the pilot bushing...I was able to turn the output shaft on the t-case to align the splines on the clutch back there too...as long as your jack is on concrete and the wheels dont hang up on pebbles,etc,it'll slide in easier than you'd expect most of the time....................................................................................................Last clutch I did ,I was about 35 years old...now that I'm 53,I might well have to take everything off and deal with them "one at a time"now,as I've gotten a lot weaker than I was back then!....I'd rather do a GM 4x4 clutch job than one on a FWD vehicle--My VW Jetta was the worst one I ever attempted alone,despite the trans being no bigger than a garden tractor transaxle--its just so awkward and needs to be "threaded" around the lower control arm bushing ,that getting it back in alone wasn't possible...had to have a helper lift it up with a strap,while I fumbled under the car with it....it sucked!...
