<VV>Overdrive

Chrysler made an overdrive 4-speed back in the '70's or '80's.  They used their standard 4 speed, left "fourth" as 1:1 but put overdrive gears in the third gear position.  Then they flipped the third/fourth shifting arm 180 degrees so when you drove and put the shifter in to third position, it actually selected the 1:1 "fourth gear" and the shifter's fourth gear position selected the overdrive "third gear".  With the single rail shifter in a Corvair it would be trickier to get the correct pattern.  The effect would not be much different then using a 3:08 and wide ratio transmission.
