While on the subject of steering columns… my P1 appears to have the extendable spring-like collar so the steering wheel can be pulled towards the driver or pushed away. However I can’t see what stops the steering wheel from just coming off in your hands – which is exactly what happened when I tried it.
Thankfully I wasn’t driving (I’m a LONG way off that point) but curious to know. I imagined there would be some kind of collar, but whatever it is, it’s missing from mine.
Neil, Marles steering boxes with solid columns and taper keyways
were used on pretty much all of the competition cars (J2/2X/R and anything
else that didn’t use a steering wheel horn push/indicator switch).The hollow/splined shafts were used on the road cars.
