YF3 Registry

1972 Chevelle Body Number Plates/Protect-O-Plates ~ Oshawa, ON. (OS)

[ 1971 ] | [ 1972 ]

It is known that in 1972 Oshawa coded trim tag style numbers with an even 3rd digit for a V8 and an odd 3rd digit for an L6 so the Fisher Body Style number is a valid resource to tell if the car was a V8 or L6.

Nothing on a 1972 Oshawa trim tag nor Warranty Protect--O-Plate card will indicate the Heavy Chevy YF3 option, RPO YF3. But, if the Fisher Body style number is NOT 13437 or the VIN does not begin with 1C37, you can be assured it is not a factory YF3 Heavy Chevy.
