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:
A49 - Front seat belt with retractor (Fremont)
B70 - Instrument Panel Pad (Fremont & Oshawa)
C08 - Vinyl top (Fremont) but top color is not specified
C06 - Folding Electric Top (Oshawa)
M20 - 4-speed transmission (Oshawa)
M35 - Powerglide transmission  (Oshawa)

 Baltimore (from Euclid plant only) & Kansas City

Codes are listed by group and in alphabetical order within the group.
