Set of 12 throttle disc (or butterfly disks if you want...) screws, enough for 2 Zenith TIN 40 carburetors as used, amongst others, on the Porsche 911.
Please note that these screws can only be used once and need to be peened to secure them into place. After they have been removed, they can NOT be re-used!
These screws are NOT shown in the drawing!
Required quantity per 2 carburettors: 1 set
