5 speed for a 1969 Dart Swinger
I was told 64 was the last year. I cannot say if that was true; but
on FABO, I have not seen a slipyoke Commando come up for sale.
Not the chart but a Allpar explanation.
From day one, there were two distinct versions of this box: A-body (later to be used in F-bodies) and B-body (also to be found in later C- and E-bodies). Initially there were three main version-to-version differences: extension housing and mains haft length, low-gear ratio and rear-flange size. The A-car box, while every bit as strong as its larger cousin, carries a 3.09-to-1 low gear, to launch small cars with even smaller mills.
For 1965 there was only one noteworthy upgrade: the 1-2 shifter fork is redesigned to ease second-gear powershifts.
In 1966, though, several important changes appeared. First (and worst), the Hurst shifter was eliminated, replaced by a hollow-shaft Inland unit. Enthusiasts generally agree that this was a giant step backward, but Joe Average liked the reverse lockout feature. Second, the ball-and-trunnion front U-joint flange was gone, replaced by a more typical sliding-spline yoke arrangement.
A new speedometer pinion setup allowed more precise calibration (earlier ones were on a small cable-mounted adapter; starting in 1966 they use larger pinions and adapters). Also, except for the very early production cars, the 8-cylinder A-bodies came with the B-car’s 2.66 first-gear ratio.
