as of today my search for Muncie-330 three speed parts is over.
I had created a Kijiji listing this past spring, and a gent from Ontario (Canada) who is not a member here, and who used to own a 1972 Lemans GT-37 reached out to me;
As it happens, (and if my memory serves me) he did a five speed swap, and although he had no intent to sell, he was offered too much to refuse and let his car go;
The buyer didn't want the three speed, and suggested he toss it.
Thankfully he didn't and several months after initiating contact (I was in no giant rush after all) it has landed in my garage -
thanks in large part to the help of a friendly PY'er who goes by 'Starlightblack'.
So I now have two complete "B" gear set Muncie three speeds, as well as one "A" code Muncie three speed that can be used in a car - so looking for more parts at this time would seem to be rather silly.
Thanks for anyone along the way that has helped me with information, or lending a hand in one way or another - I am very appreciative of it all.
I hope to be as helpful to other members in the future.
