Shows what you found: base 6 cylinder 3 speed C10 uses a different ' synchromesh ' then all of the other C 10-30 series. The description of the three speeds available is very vague. They show a single picture to represent all of the three speeds available and it happens to be the older 4 bolt Muncie pictured (?!) Makes no sense at all (?)

I own a very typical almost zero option '67 C10 with the base 250 6cylinder and three speed on the column. My truck has the Warner (NOT a Saginaw NOT a 4 bolt Muncie) three speed column shift that I believe has an 8 bolt side cover and does not have a synchronized first gear. Everything about this truck looks completely original and unmolested. I'll try to get some pictures of this if I'm at the house this weekend.
