b2200 driveshaft / tranny question

We are in the process of bagging my friends b2200 and he wants to know exactly where the driveshaft should be at ride height. He wants to make sure that when he lays out the driveshaft doesn't shove into the tranny causing problems. Here is a pic of where it is now (ride hight). I am guessing it's pulled out 1/2 inch from where it was stock. Can anyone give us a tip of how far it should be in/out or if it should be where it was stock. Thanks.

Oh yeah, we are running a triangulated 4-link in case you need to know.

its a slip joint, so as long as you set up the four link not to pull the axle forward or back more than the operation arc it wont move at all. I just stuck mine in to the dirt mark that was on it and set up my four link, I get about 13 inches of travel without moving the driveshaft at all.

alright, we were going to put it there, but wanted to make sure before we had everything all welded up, thanks
