1970 340 Duster rare x car.

Look it up,fender code n-23 electronic ign.70-71 its a fact do you need a link to mopar codes to see it . Its there go look again that is code n-23 factory option in 1970 so where are you getting your facts ?

WRONG

N23 wasn't on the tags until 1972 (STD equip on 340 cars) IIRC and NEVER on 1970 cars.

Been spending time at some of the sites with fender tag info that is WRONG I see. Maybe mymopar.com :)

LOL

If you want help looking in a 70-71 parts book, distributors are under 8-27-1. NOT A SINGLE non points distributor listed for EITHER year.
