I purchased my DII in Aug of 2000, and started modifying it about two months later. After all I have done so far, I still have several things planned, so stay tuned. It's my daily driver and my primary family transport. The mods I've made to date are:

Modified front and rear radius arm bushings
Bearmach front differential guard
