70 Duster 340 production numbers question

Tom,

I don't think anybody can come up with an accurate production total on the
Code #J81 'Go-Wing' Spoiler Option.

One thing, there were virtually none on the 1970 'Duster 340', especially in the
Northeast.

I saw a lot of 1970 Duster 340's, and I don't ever remember seeing one with a
Go-Wing Spoiler.

My car was actually sold up at an Oregon dealership. SE part of the state in the desert. (technically semi-arid) :) I always recall seeing them more on '71 Dusters and Demons myself.

I've heard so much about that being a dealer install, but since it seems so difficult to verify I kinda gave up.
