No i don't... that's why i'm searching for those answers but i had an answer from Barry Washington :
"V08 was used for non-recommended color / trim combinations and FY1 & V1G was fine according to the trim book. But, the trim books were printed prior to the start of the model year & were subject to edits. I do not have all the edits or one that mentions this change yet. I am also aware of two other 1970 model year cars that have the FY1 V1G codes & both of them also show V08. One is a Cuda 340 & the other is a Challenger R/T SE with the 383."
So it's sound like that color with the vinyl top wasn't meant to be at the beginning, but was fine for the LA plant, i guess. It's what Russ wrote earlier.
