'64 Dart 4 Speed Synchro Replace Mandatory Parts List?

It's nice to know these transmissions are at the opposite end of the spectrum from, say a Force outboard motor. :) Your methods are till great food for thought. One of those thoughts is if 2nd gear is the most used, and new synchros can prove problematic, does it make sense to use the old synchros from 3rd and 4th (that engage fine) on 1st and 2nd and put new ones on 3rd and 4th? With this 245 rear end, 1st gear intersection turns are going to be the norm.
