Genuine original Bosch dual-port distributor vacuum advance/retard unit for the 1980–1983 U.S.-spec Porsche 911 SC.
This is the correct original Bosch unit stamped 2763, corresponding to Bosch part number 1 237 122 763 and Porsche part number 930 602 915 01.
Both vacuum ports were individually tested, and both chambers hold vacuum properly. This is an original Bosch component—not an aftermarket reproduction.

The housing and mounting bracket show age-related surface oxidation, discoloration and normal cosmetic wear from previous installation. It has intentionally not been polished or refinished in order to preserve its original appearance. Please review all photographs closely for the exact condition.
Original Bosch units are discontinued and increasingly difficult to find in tested working condition. This would be an excellent choice for maintaining or restoring an original Porsche 911 SC without installing a modern aftermarket replacement.
Only the exact part pictured is included. Please confirm the stamped number, mounting points, vacuum-port configuration and vehicle application before purchasing.
This will be shipped to UPS ground with signature requirements in accordance with ’s shipping policy. It will be packaged very well.
Please check the last two photos with the vacuum pump holding vacuum.
Thank you so much for looking and have a great day!
