ALL 1971 A51 DUSTER TWISTER OWNERS, need help with stripe decoding!!!

Ok, so here it goes! I have 2 A51 DUSTER TWISTERS, and neither have the V6* Stripe option on the tag.....is this because they were definitely on the car because they were part of the Twister package??? Both cars have the V8?* Stripe options on the data tag, so both cars came with the rear stripes, ok, that I understand. NOW FOR THE TWIST......my EV2 car has the V8X rear stripes, and then has the V9X stripe code after that, which decodes as the Longitudinal Black tape stripe where my other car does not have any V6* or V9* stripe codes....any help would be appreciated!!!
-ps....both Hamtramck built cars as well....
