Vacuum Advance / Boost Retard unit

ok so I've found a couple of part numbers...

vc1309 / CV1867 - VW / audi unit

Preliminary investigation is interesting, but today at lunch I had a productive junk yard run.
I pulled a stock mopar unit in the first 5 min, and after exhausting almost all of the rows, a set of volvo headlights caught my eye. The volvo gave up the goods in short order and upon arriving at the checkout counter, the gentleman said "what are those?" I replied, "vacuum canisters"...So he says "have a nice day".... :D

It probably helps that I go there all of the time "looking" but don't seem to find anything very often

So now I have a stock mopar one to hack up and a working vac-advance / boost-retard unit....for FREE!!!! ( well, it cost me $2 to get in ) I even pulled the vac line with check valve too.
