Did a bit of rework on the t-case linkage. Got rid of that stupid transfer linkage and went direct from the shifter to the t-case. A have approx $15 in this mod. Much more firm but need to move the hole for the shifter down about 1/2" to get 4 low. Not a big deal, it has everything else nice and solid but pops out of 4 low. It was a guessing game seeing I didn't have the stock Jeep t-case arm. Found the joints at Tractor Supply (MTD4415168) and the 3/8x24 threaded rod from NAPA.
