Here's reviving a old thread. I have been researching this color as my car has it, I think. It is paint code 99 99. It has a build date of Nov 21 which I believe is in 1968 making it a fairly early car and certainly not in the spring where I live! This is the only pic I have access to right now but the sequence number under the bolt is 123417. This would make me think sp stood for special not spring. But I'm still learning about it. I am trying to add a link to photobucket but I'm not very good at this stuff!
I've been tracking 1969 99 paint cars.
Beginning in October and through December, it appears there was a sizeable number of green and orange Road Runners built at the LA plant.
99 'Green' was not a 'spring only' release. Cars in that color are found in the fall of '68.
Given the small production at the LA plant, 99 paint Road Runners, as a percentage of cars produced, seems to run much higher than the Lynch Road or ST. Louis Plant.
