I am considering buy an "advertised" 67 RSSS. I have reviewed some trim tag decoders and I am not so sure it's legit? Can someone help? Top line of the trim tag = 10B which I believe is the 2nd week of October followed by a 6690 which I believe is the assembly number from that plant. Line two is 67-12437 followed by LOS then 4169. Line three is 760-Z with a RR to the far right. Line four is W 2WG... that pretty much it... Thoughts??
