One question, I have been told it has a Muncie 4speed. How do I determine exactly what it is? It is definately a 4 speed and not a granny top loader, but I had a 4 speed in my old 69 chevy that I ended up pulling out in favor of the 3 speed it originally had because the 4 speed was so closely geared. I was told that one was a Saginaw but I don't know the difference in them. I have always been told I should be looking for a "Rock Crusher" Muncie, which I assume would be the M21, but I don't know how to identify it.
