....and I have not pulled anything heavy, but this is a 1966 M35, and was a pasture survivor, and used as a mudder there before I saved her, so it is quite possible she pulled loads within the last few years, I just don’t know. But maybe the synchros can tell us their story.......
I drove her in 1, 2, 3 and 4th gears today, but only could shift when stopped. And today, it went back to sometimes not allowing me this time to get OUT of 2nd gear, even when stopped and the clutch pushed to the floor. All other gears were accessible except 2nd gear -- it was the bad actor that would not let me come out of 2nd or into second without going into 3rd or another gear, gently lifting the clutch, then trying 2nd again. In my mind that helps align the synchros, but who knows. It seems to help 2nd. I energetically drove her for an hour in the pasture (most fun in a long time in the Deuce...!) and then into the shop and removed the top plate. Lots of photos attached. Bottom line -- ALL of the synchros are definitely reddish-colored. They are not and were not ever yellow as in the photo that was sent. I gently steel-wooled a small place as seen in the photo (and caught all the stuff coming off) to check the under-lying color and it is about as COPPER colored as you can get. Maybe bronze or rose-gold, but not yellow. I inspected the synchros as best as possible, and could see no markings whatsoever. I could, however, only see about 30% of their surfaces.
In the photos, I took some close-ups of a few areas of obvious wear. Also, if you see my fingers in the photo, look at the next photo, and it will tell you how much TRAVEL that piece has. I don't know when transmission parts movement becomes SLOP.
I understand that all synchros wouldn't go bad at the same moment in time -- but this truck will not shift into any gear while in motion with clutch to the floor. I did confirm that I am always pushing the clutch to the floor. On that topic, I have about 2 inches of travel from the floor to the beginning of engagement, and then maybe 3 inches more of travel as the clutch fully engages somewhere in that travel. We race cars with heavy clutches, and this clutch seems to be functioning perfectly. Seems to be in the gearbox.
My SWAG is one or more synchros are bad, but they dont all go bad at once, and they do operate independently, don't they?
THANK YOU. I know we will figure this out.

THANK YOU. I know we will figure this out. Will post photos in the next Reply — having a technical issue.
