Muncie ID ?
It's a 3925660 = 1968 - 1970
3088336 = ?
Tail 3857584 which makes it a 27 Spline ?
Date Code P9R10 or P9P10 = 1969 Dec 10 ?
BUT the Date Code Does NOT Show a "A" or "B" or "C" for M20 / M21 / M22
It's just NOT There
So how would I ID it as M20 M21 M22 without going inside ?
or you can't ?
Thx
