I believe one of the links shows how to do the cable normal-E-drive. I would not use the crown or omix-Ada chain. One of the CJ guys bought one and it stretched worst the the one he replaced, in 4 hours.
Send a PM to skizriz and ask him where to get a good chain. You could also check the slop before swapping the chain.

The QT is a great unit as long as you keep a good chain in it. Lots of FSJ's where sent to the scrap heap because of a broken chain. Once the chain breaks it usually takes out the case near the lower gear as the chain bunches up and the gear still tries to spin. Not much extra room down there for that and pop!

The chain service interval is 60,000 miles. The good thing is that the chain is easy to change. Almost, like someone was thinking.

The QT was originally designed for military service so it is good and strong. I did have a cone clutch go out on mine. I had a old timer jeep mechanic help me get it back together and running. He told me that if I am on any loose ground to go ahead and put it in emergency drive, it keeps the strain off the cone clutches.

In the back of my mind, I'm always worrying about my q-trac, but it hasn't let me down yet! Chain has over an inch of slack, but have never had any problems. It does super awesome driving around town in the snow. Has only gotten stuck going through things that I shouldn't have been going through, and that would stop most people.
My plan is to run mine until I get a new chain and put the milemarker o/d kit in it.

Beauty is in the eye of the jeepowner.

The thought of a grenaded case scares me. I had similar feeling about a 1.8t Jetta I had once. Felt like I should replace the t-belt just be safe. It gave out a few weeks after I bought it. Ruined the head.

I think I'll replace mine just to be safe

Probably easier to replace than the t-belt in a Jetta!

QT is very strong. Huge chains compared to today's chain drive cases. The weak part is the aluminum case. I had a QT in my old trail rig and wheeled everything including hard core rocks. Never one problem. Had a part time kit too. I was hard on it, treated it like I stole it, and it kept on keepin on. I did put a new chain in it before I swapped it in. Oh yeah, it was in a YJ. Yes I swapped a QT into a YJ.

You can swap the T-case and still use your offset rear-end. The drive shaft will still clear. A Dana 20 would be a good swap for you. They came with them from the factory. Go to IFSJA.net , lots of info there.

Why me, Why me !!!
