Working on a 1970 Cuda, 426 hemi, automatic. It has a cast iron dual point distributor with an aftermarket tag(rebuilt?) and no other numbers. Somewhere along the line, someone replaced the points with a Pertronix unit that I believe has gone bad. Pertronix can't do anything without the distributor number. What would be the correct part number for the distributor in a 1970 426/auto Cuda?

[SOLD] - MOPAR REFURBISHED DISTRIBUTORS

OK Have a finished Dist list. Still doing inventory after Carlisle. All are completely disassembled all tolerances check, ant item fixed reassembled and run on a sun distributor tester to document the curve either factory or custom. Also have tons of pre 90's ignition parts if needed. Some...

I show a '70 model uses a 2875987 for a manual trans, and 2875989 for an automatic. A replacement partial part is one digit higher on both numbers.

Those numbers are for a manual transmission. THe OP is asking about an automatic.
 
I have a Galen book. It could be wrong. :BangHead: The good thing, the tune up parts and Pertronix parts should be the same.
 
Parts are the same Mike you got it on the 70 hemi list. 4bbl 6 bbl 2x4 bbl Build date all needed also
 
It's my understanding that Galen was just one of the many people allowed to get anything left in the archives.
I have a copy of his 64-72 castings, which has not been wrong except for 1 possible instance.
 
I caught a few in the dist section but still a great list.

Pet 1385 should be the unit needed.
 
Thanks very much for all the info guys! I just purchased a 2875989 distributor off Ebay for the owner of the car. Come to discover, whoever did the Pertronix conversion did NOT change the coil. It should have a .6 ohm coil but it has a 2.0 ohm coil. Tech at Pertronix tells me that is a big no no! Rest of the story is, I have to have this car running before the transport gets here to take it to a restoration shop for some very minor body issues. The proper coil should fix the drive-ability issue for the time being, and I can get the distributor rebuilt and ready to go when it gets back.
 
If you are trying to be "restore" accurate, you have to be careful. It may be (not sure, just as EG) that some CA vehicles had different dist's than federally and also for different options. Some long about 70 / later had the electric retard on the vacuum advance.
