About the GM shifters (‘64-’72 A-Body cars)

Ok, so there’s a lot of discussion about shifter locations and shifter setup on the GM cars.  This page is specifically dealing with the ‘64-’72 GM A-body cars.

The intent of this page is to assist you with installing a TREMEC TR-3550 5 speed into your car.  It’s still a ‘work in progress’, so please stop back again sometime.                             

Special thanks to Dale McIntosh for helping with this information!  See his website at www.team67.com

The 66/67 A-body cars have the shifter about 3” off-center towards the driver.  The ‘68-’72 cars have the shifter centered in the tunnel.   It's not so much that the shifter is to the side but I don't believe the console is as wide on the 66/67 models.

Note the 68 uses the same shifter unit as the 69-72 but the same installation kit for 64-67. Early Muncie's used bolts to secure the shift arms to the trans while later ones used studs/nuts. 

It’s also possible to use the 69-72 installation kit with a 64-67 shifter assembly. This would help you use a later transmission in an older car.
