Hey everyone. I have an original 307 in my '69 along with what I believe is the original (probably rebuilt at some time) 3 OTT. Were there different models of 3-speeds on our trucks? And if so how do I go about ID which one I have?

Thanks in advance.

Count the bolts on the shift cover. 7 bolts is a full synchro saginaw.
