Vacuum Advance Unit for 83-85 1.9L Vanagon Distributor

Vacuum Advance/Retard Unit for 83-85 1.9L Vanagon. Has two vacuum ports on it. This part has been discontinued. 

My current recommendation is to buy a complete new distributor that includes a brand new Bosch Vacuum unit.  We have those for sale here:
