What model dist.?? If you are using two-piece points,the cap with the locating lug and semi circle cutout,you are probably looking for the rotor that is secured with a set screw.I believe that OKParts # AR 40 007 002 is the one.Classicalfa sells a less expensive repro. Both of these are in the 105 series section.

 

Points and condenser are the same as for a four cylinder Porsche of the era. Should be easy to find in the USA, maybe even at your local foreign car parts store. I suspect that the same is true of other distributor parts for your Alfa.

 

I just bought rotors for the JF41 distributor in the Sprint from Classic Alfa. Quality seems ok but not on par with the remaining new Bosch rotor on hand. I could not find any domestic source for these rotors that are secured with a screw. This was definitely not the case four or five years ago.

 

The rotor might be unique to the Alfa distributor. So take care of the one that you have! They shouldn't need replacement very often. The solution might be to replace the cam piece with one that has the notch for a push on rotor, but I have no idea of what complications that might entail.

 

It is a Bosch VJ 4 BR 35.

Thanks for the tip on Porsche Tom.

 

Here's my VJ4 BR35. The new rotor is from Classicalfa,but I'm not sure that this is what they're offering now. OKparts has a Bosch pictured on their website.If you find something else in the states that will work,please let us know.Toms' idea could work if you're not using points(electronicPertronix,etc.,)and rotor points directly to a plug(and not half way in between!)but lobe design and direction could be a huge problem,especially with points.I wouldn't doubt that a push-on could be found that fits, and then drill a set screw hole.But I believe that this rotor has a resistor built into it,so that's another concern.Regards,Phil D

 

The local Porsche dealer asked what model Porsche the points were for-any thoughts?

 

Any year, 1960-65, 356B or 356C should work. It might be convenient to mail order these from Stoddard, Zim's or Pelican.

The ones in my 1959 356A look like they'll work, but my Bosch parts catalog does not go this far back.

 

The points can possibly be sourced at a VW supply house. You need a set of split points (2 parts). What is going to be difficult is sourcing a condenser that is close to the original. If you go to far from the original, the points can burn. Take the original with you or have it on hand when someone asks you what the number is on it. It will also state the ohms, this is the critical part. There is a VW shop not to far from me, I can ask them what they suggest.
When my Super died on me one night driving home, the condenser was so old it just died. Left me stranded a couple miles from home. After making the round trip with a new cap, rotor and coil, the car refused to run. The next day I determined the distributor was bad and swapped it out. The result was a bad condenser. Put in a new one close to the original and never had another problem.

The problem is the gel inside between the papers dried out, shorting it internally.

 

I Looked Thru My Stash Of Bosch Ignition Parts (spares for a 1600 veloce) And Found The Following:

Bosch Rotor With Set Screw Mounting #1234332141

Bosch Points #1237013060 (lists 911, L, T, S 09/64 - 07/68 on back)

Aftermarket (EFFE) Condenser (Made In Italy) #3641

Hope This Helps.

Many thanks John; I will see what the local Porsche dealer can do with these numbers.

 

It might help to know that the Pertronix #1844 is a drop in fit as well as the ignitorII,91844.I'm told both for certain 356s' and 912s'
