I just did a first through third syncro rebuild on mine. The Haynes manual does a good job of going through the steps, with the exception of that nail trick to get the speedo drive off, (must have been an inside joke) a deep socket is a must for that.

Second and third gears are on the same shaft back to back. Mine was hard to get into first, second, and starting to in third. The grinding is not the gears themselves, but the "dog teeth" ring pressed onto the gear and part of the slider ring. I replaced the syncros for first through third and the dog teeth on second. These parts all showed signs of excessive wear. The special tool I used for the job were: deep socket for speedo drive bolt(pinion expansion bolt); syncro "dog" teeth remover/installer; and the plastic block to simulate the intermedate plate (use to align the two gear shaft so the shift forks can be adjusted). Parts and tools ran about $300.
