Mike,
COOL!!! Those pesky one way pins.....whoodakno!!!
OK, be sure not to do what I did with the center heim/trunion joint! When you put he shifter in 2cnd or 4th check the clearance at the firewall thru-hole to make sure that you are not "too close" to the tube that passes thru the firewall..... Mine was fine....., then I "optimized my center trunion height by eyeball.....wrongo! I guess I lowered the shaft a bit.....
With the rubber boot installed, I ran into "too much stuff in the hole" and that being so, would interfere with trying to get fully into 4th or 2cnd gear!!! The fix was to simply "raise" the center trunion until everyone was happy again!!! (With no boot.....it was fine......!!!) 2 & 4 felt a bit spongy at the end of the shift...arm didn't go all the way forward in the gate.....shoulda been the first couple of clues that things were amiss!
Shifter adjustment is easy. Center it R-L and snug the nuts a tad, then center it Fore-Aft in the middle of the shifter gate, adjusting length as needed, rinse....repeat.... until it is centered at rest, L-R & F-A. Then you should be golden!!!!
In my case, I pulled my ZF out to look for issues and magically found NONE related to my shifting! I did find a crazy problem with my input shaft bearing being out of place however, and I replaced 1st and 2cnd gear blocking rings whilst I was in there! So all was good! Put it back in and didn't fix a thing! That's when I just sat and stared at it for a LONG time.....until I traced the shifter shaft back to the firewall.....pulled that boot back and it worked fine!!!! DOH! Adjusted the trunion joint higher......and went for a drive without worrying about 2cnd or 4th popping out of gear any more!!!!! 
Cheers!
Steve
