Yea, its starting to sound like the shake is further back in the system. What about running up in gear with the T-case in neutral? No shakes there would completely clear your tranny of any blame.

Manic, that is what i have been looking for pics thank you. Mine is absolutely a single mass as i had it out a few months ago.
Northern, i will try the t-case in neutral this afternoon and see what happens that is a good idea

Awesome! Ok now you said you reused the N/A's flywheel right? As I posted before you'll need to get a single mass flywheel from a "K" vin truck (turbo IDI). The best part is it won't cost you almost a grand. It'll be more around $300, if that. Hell if you find a good condition used one those usually go for less then $100.

Tried this and with the t-case in neutral, tranny in first and throttle at 2500 i get a worse vibration than just in neutral or clutch in and in gear. What does this mean???

If the flywheel is the issue, the engine should be unbalanced when revving up in neutral, as the flywheel is spinning. Since this is not the case, the vibration seems to be coming from further back in the driveline. Your suspicion of the T-case damage may be worth following up on.
That being said, Rock Auto has solid flywheel conversions for $124.73 and I verified they have them with part numbers specific to the K model (factory turbo IDI), so I think at that price I'll be ordering a new one anyway.

This is interesting, I just searched flywheels to see if I put any sealer on the flywheel bolts and came across this. I'm doing the opposite of the original poster. I'm putting an older 6.9 in a 93 IDI turbo. I have to use the flywheel of the turbo 7.3. Mine is the dual mass. Kind of nervous about using it now.
Where you at, maybe we need to swap flywheels. But also sounds like it may not be your vibration too.
