It can be done in your existing distributor letting you keep the tach drive. My 300F had this done in 1982 by the previous owner. Exactly how, I can't tell you because I didn't do it but a competent electrical shop can. I didn't know I had the Mopar electronic conversion kit until the late 90's when I discovered the orange brain box installed under the battery box. Only then did I pop the dist. cap and find zero points underneath. Could email you a photo if that would help. [Non-text portions of this message have been removed]
