Who made the rocker arms for Porsche originally?
With a ‘manufacturer-like’ quantity, the cost should be reasonable.
They were in the US$20 range ('retail') in the late ‘60s.
The current ‘market’ is because Porsche chooses to not support their ‘old’ products.
Are replacement caps of same or better quality than original?
The hardness issue is due to the very high pressures at the rocker contact.
I need to supplement my set.
These were all from Frau Baer, decades ago.
Best,
