Dillinger adjustable UCA setup

Finally after a year of having these parts and life getting in the way I FINALLY am getting these in. I have the Dillinger adjustable UCA's and was wondering what people have done for the initial setup of these. What I'm wondering specifically is how many threads do you have showing above the lock nut on the threaded eyes both front and back? I really don't want to have to take these off a bazillion times to get it where I can have an alignment done.

Any input would be appreciated
