#451 ('63-'68)- shift arms attach w/stud and nuts.
#452 ('69-up) shift arms attach w/bolts.
No grooves or number of grooves if present on input shaft can indicate ratios.
There were several different 4 speed Hurst shifters used depending on application.

The transmissions all have the same dimentions, it's the shifters that are different. Some think that just because it's a Hurst shifter it will work on any car.WRONG.

Don't forget your speedometer drive should be on the drivers side of the tailshaft housing for a Pontiac of this vintage
