Russell, Some synchro assemblies had a mark on the clutch gear hub AND on the sleeve. These were to be put in alignment. This was determined at the factory to give the smoothest & least sliding spline resistance under load when the two pieces were indexed in that position. I would probably try them by hand in all the spline positions & if some seemed a looser fit, I'd use that position. More likely, they'll seem all about the same, so just pick a spot & go with it.
Did you get new brass blocker rings? I like to have a new one just to compare the others with. Any doubt, I'd replace them. These are pretty heavy 1st & 2nd gears & put a pretty good load on them. My driving style is to double-clutch on a 1st or 2nd gear downshift.
Hopefully your mainshaft nose is in good shape. I've got a pic of a bad one in my album below.
Hope this helps - Doug
