> Has anyone reclocked thier Dana 300 in a 1979 CJ-7 ?
79's came with Dana 20's, not Dana 300's.
> It sounds like a pretty good idea, you get better ground clearence.
Yes and no. The clocking by itself doesn't improve ground clearance. It's the removal of the section of the skid plate that dips down that gets you better ground clearance.
> Any input would be greatly appreciated, like linkage or front dive shaft angles, skid plate.
The linkage chabges position slightly, front driveshaft angle is a bit steeper, and you can get rid of the dip in the skid plate.
> I have a 304 with Dana 300 and T-18
If that is what you have, then there is an adapter between the T-18 and Dana 300 and that adapter will determine whether or not you can clock your t-case.
