hello. I have an '85 berlinetta and I have 5 RPO codes that I can't find proper codes for.

FA1 - closest I can find is that this is for a 12,000kg dual speed rear axle. that doesn't make much sense on a Camaro.

FA2 - this one says its for a 14,000kg dual speed rear axle. again, doesn't make sense. also, last time I checked my Camaro had only one rear axle... lol

GA1 - this claims to be "fleet incentive - the alterwoods group". I have no idea what that even means

GA2 - another 'fleet incentive'. this one says echo star/dish installation network

15M - I have found nothing related to this code, either.

for FA1, FA2, GA1, GA2, the only source I have found references to these codes are from www.longroof.info/pdf/rpo.pdf but that's a list for all chevy's or GM's it would seem, and I know some codes are used for different things from time to time. also, I do not believe i'm reading these wrong, but just in case I have included a pic of my RPO sticker. any help would be much appreciated! thank you.


edit: I realized I did actually read one wrong so I just removed it from this post.
