Heater knob variations


Recommended Posts

While going through some spare parts I found a heater know unlike the ones commonly seen on the S30, the lower knob in the photos below.

Has anyone seen the use of this knob on a S30 (or any other Datsun)?

The upper knob is what I have on my 7/70, used up to 6/72. The more rounded one is used after that for 240's. There are other versions used on 260's and 280's. If I'm not mistaken the later ones used on 280's (maybe 260's) are just push on and don't require a screw. The push on ones also work on the 240Z controls, I have a heater control set from a 12/70 parts car that has them. Must have been installed by the previous owner.
