How much do I need to shorten driveshaft?

[74kay5]

I did a 4L80E swap among other things and stuck my driveshaft into the NP241 T-case I'm using and this is where I'm at. It goes pretty damn far in there so I'm afraid of it damaging the case. How much clearance do you generally see when looking at the driveshaft mounted to the back of the case? I marked where it stoped going in (give or take 1/8 of an inch). Could I actually be alright with the way it is?

where's it at when the driveshaft is installed?

All the shaft to the right of the whiteout marked line is in the transfer case at this point if it's mounted.

Yeah I think thats too short expecially if you have flexy rear suspension. BTW I hope you clean up that slip yoke. That's hard on the seal

The swap took a little while so the drive shaft was sitting. I'll get all that rust off before I mount it permanatly

It's too short?

to get an exact measurement take the slip-yoke off of the driveshaft, insert yoke about 1/2 way and measure (from center to center) from rear end to yoke. then you'll know exactly what length shaft you'll need.

amazing how sleep helps the thinking process.

So half way in is what I how it should rest? I just dont want to cut it too short and go over a bump, have the driveshaft fly out and drain my T-case fluid. I've seen it happen a few times.
