sorry

"Have prev mentioned on this site, there is a "no groove" 26 spline M21 input shaft that can be confused with a fine spline M22 input shaft. From the dozens of Muncies I've had in here, the M21 input shaft is a later replacement piece from the late '70's-80's. Have had two of these no cut M21 fine spline input shafts; & curently have a '72 M21 in the rack so equipped."

I thought we were talkin 70 ?? 10/27 spline ,,,,, ?? no groove input
bein' the car is a 70

nice find mistic missle .....
we just picked up a 70 GTO built at the Oshawa plant and its RUFFFF also
