The 1973 2.0 used an 8mm adjusting screw that almost never wore PN 039.109.451.
No longer available. The contact area to the valve was much larger than the other 8mm screws. I don't ever remember replacing these screws due to pitting and worn areas that the small contact 8mm screws and especially the 10mm adjusting screws failed with. These adjusting screws will also help prevent pitting and damage to the valve stems. Changing to the "wobble foot" 911 8mm valve screw requires grinding the rocker arm, respacing the rocker assembly and resetting the geometry to correctly install. These used adjusting screws will require 8mm rocker arms but will require only regular valve adjustments. Lock nuts are included, $100. Shipped SOLD, Thanks! Attached thumbnail(s)
