PMD Walnut Shifter Knobs
Short answer: The correct “PMD” walnut knobs for a 1968 with M/T floor shift:
- 3-speed: “Pontiac Motor Division” with red crest — pt# 9794301
- 4-speed: “Pontiac Motor Division” with shift pattern — pt# 9794300
Custom Gearshift Knob was option code 524. There are reports of the earlier 1966–67 “GTO crest” knob on 1967/68 Firebirds — likely from dealer stock; it’s doubtful any 1968 Firebird left the factory with a GTO-crest 4-speed knob.

← Frequently Asked Questions
I bought a 68 Firebird in 2002. The car was never restored and it’s a true numbers matching car with 2 build sheets found and registration cards from the original owner.
The car had the GTO shifter knob on top of the Hurst shifter. I thought it was a mistake but read somewhere the knobs may have been used in Firebirds.
Is there any information to back this up?
Assuming manual 4-speed ball shifter knob.
Were you able to decipher the build sheets? It is very unlikely ordered from the factory. The broadcast sheets may/may not shed some light on it. Pictures?
The 1967 – 1968 Shifter Knob Ball, White 4 Speed, has the smaller 5/16 Inch Thread size (attached picture). White was used for light colored seats. Black used for dark colored seats.
I believe the 1968 GTO used a 3/8 thread size.
