DM2 eh, just shows that Google isn’t always accurate 🙄
At least you now know what it should be
Retro Classics can build a vacum unit apparently http://www.retroclassiccarparts.com/vacuum-unit-25d4-25d6-and-22d6 if you don’t want to wait for a distributor overhaul.
Just phone with the three numbers off your old vacuum unit or the model and year of your car and we will make you a new one
