Confidence

For me it's the prospect of an eventual gear swap (3.23 to 3.91) and adding a sure-grip/truetrak to my 742. I've never worked on a differential and know there is an element of finesse to set it up properly. I'd love to learn how to set-up a 742 as it'd be great to be able to swap gears for different applications, i.e. long highway trip, 1/4 mile action etc. But, unless I can find a local FABO member that knows the ropes and is willing to walk me through it, I'll probably end up having to pay a "pro" to do it. That said, I still have plenty of other "to-do" items to keep me busy for awhile.
