Well i was fortunate for a while, lol, it worked a little better but is now acting up again, grinding bad going into 4th, we have checked everything out on the outside, linkage bolts, shifter alignment etc,, it's coming back out to see whats wrong s***!. In the meantime i'll put back in my m-20 wide ratio.

When you get it apart I would look closely at the keys and springs in the hub assembly. maybe binding ?or a 63-65 synchro used with a later model hub.The hub and synchro have to be from the same family.63-65 uses non shouldered brass and 1-1/8 wide hub.66-74 shouldered brass 1 inch hub.You can use either matched assembly in either years of transmission but synchro must match hub.

Thanks again, we will look into that when it's apart on his bench, will let you know what he finds, he's been rebuilding muncies for years, you never know maybe he forgot somthing.

This is a replay of a bad dream I had ~22 years ago. Means your back at (my) Post #6.
