Pardon my lack of knowledge on this subject, but are you referring to the stick shift RTO. I don't remember where of course, but within the past couple days I've seen one. It was removed from a roll-off truck with about 186,000 miles while still in working condition, replaced with a different type of transmission.
I'll look for it. The photo was really poor and it's in an add that didn't look like anything important. Easy to miss.
