    I've been driving my '64 A100, slant six with 3 on the tree, had it about a month.
    No syncros on first on it. Have to come to an almost full stop before putting it in first.
    Second and third are fine.

    Yeah, that's the best way. It will stop the grinding. I cheat a little, but for all intents and purposes, I'm stopped. You'll get the hang of it.

    anyone has an exploded view or plans of that fully synchro? i have a A-745, could it be changed to synchro by changing some gears?

    the v-8 trans might have full syncro's. they are called an a-903. you could have either one but i know of the 2 possibilities. i have a spare and never looked to see what it is.

    the visual diference between the a-745 or the a-903 are the little bump on the 745 door on top of it, but i tought the a-903 was the regualr duty(car ) and the 745 the heavy duty( light truck and taxi and police....) so the a-903 is the synchro one???
