Certified, that was a great read. And I'm glad you made it to LOG. Since I read a speedrun through your build speedrun to get clues about adjusting the shift mechanism, I thought I'd give a bit back by indexing what I found on the subject.
[Assuming everyone has the same pagination, currently at 89 pages...]
Pages 15-18 Decide whether to rebuild the linkage or move to a cable shifter
Pages 37-40 Assembly
Page 60 Final adjustment
It turned out I was in pretty good shape, just needing to replace the tophat washer/bushings up front. So, aside from documenting everything, thanks for easing my mind on th subject.
