Accessory ~ Fremont & Oshawa Similar to group option codes on other 1965 plants but Fremont & Oshawa used the Regular Production Option (RPO) code. Canada also lists the convertible top code here if applicable. I've seen formats like TOP-2, TP-2, T-02, etc. for a black convertible top or TOP10 for a white convertible top. Common RPO codes found include: |
Baltimore (from Euclid plant only) & Kansas City
Codes are listed by group and in alphabetical order within the group.
If you know of any codes not listed here, please email me with details - (1) year, (2) body date, (3) plant, (4) group number, (5) letter code, (6) option if known, and a photo of the tag would be appreciated.
