Distributor shaft length and interchange question

[troy.70R/T]

I am putting a 67 383 in my Charger. It is a points Distributor but I have several Electronic ones but I don't know what they came out of. How can I tell if one of them will work in my 383. Is it just a mater of the length of the disturbtor drive shaft?

Assuming they are big block Mopar units, yes its just the shaft length.

[troy.70R/T]

Yes they are all big block. what length shaft do I need for a 383?

[troy.70R/T]

I guess once I take the points dist out I can match up the  lengths.

[RallyeMike]

Yup. Tthere are only two length, and the difference is significant. It will be obvious.
