Hi, Still looking for anyone with any suggestions to what these numbers could decode to. I seen on another forum a early 69 z28 had a LG7 on the bulkhead and the owner said it had a rare light green interior color which would maybe confirm the LG (light green) and he said the 7 decodes to z28 without style trim, and I am not sure of the validity of that. Also another owner chimed in and said he had a LG1 on his bulkhead and his would decode as LG (light green) with a 1 meaning car with style trim or RS. So I was wandering if my 8 and 1 could mean z28 with style trim for my car which would be correct. Just throwing that out there. Thanks, Michael
