911SC Ign Dist Comparison ?

[BoxsterGT]

I have two 911 SC Ign Distributors in good working condition w vacuum advance.

One is a 0 237 301 007 (PGFUD6) and the other is a 0 237 306 001 (PGFU6).

Can anyone tell me the difference between them?

I think they are both suitable enough for using with Weber or PMO Carbs, but would like an opinion from someone more knowledgable on the subject.

Thanks In Advance,

Len

There both good for carbs, send them to berry hershon in detroit and get them rebuilt for carbs with a total of around 35• advance and no vacuum. Great for power
