I found the numbers on the amount of standard shifts, as I recall there were less than a couple thousand per year manufactured. Before I installed the Muncie I did quite a bit of research and I found one in Texas on craigslist and I offered to buy it as a donor for mine. The guy backed out of the deal. I found another on craigslist in PA and it was gone the next day. I then found a guy in the Midwest and he had a couple of them. We corresponded a couple times via email and I never heard back. Needless to say they are rare with a lot having a 3 speed saginaw. I have never seen an original. Welcome to the forum from SW Georgia
