That's what I'm thinking BD, FYI since you moved the body up and in effect moved the shifter down it will make the boot move a longer distance during shifting. This will cause the boots of both the shifter and the t-case to hit each other and will push the t-case out of gear when it's in 4wd low. The best way to fix this issue is to just push the shifter boot all the way down past the large section of the shifter.
