I have 505 vac cans, but that's only an fuel economy part and would 
not cause your symptoms.

Your best eventual distributor solution would be to send both 
distributors to me sometime when you could do without the car for 10 
days. I could swap everything over to the '73 dist, including the 
Pertronix, and install a correct 505 vac can.

When I was working on figuring out how to adjust the FI trigger 
points, several people on this list were good enough to send me some 
NOS and very new trigger points for comparison. The NOS set was 
non-Bosch, the only such set I've ever seen, and it was totally out 
of whack. (That's the technical term.) It would never have worked at 
all, until I adjusted it.

I'm not a fan of NOS. I'm afraid lots of people see NOS as the holy 
grail and are willing to spend big bucks on such things, when good 
used (and tested/proven) parts are cheap. About the only parts I will 
routinely replace are exhaust valves. Everything else gets 
tested/inspected and reused or replaced with good parts, new or used.
