All 63 & 64 Impalas had flags(327 Cars) and v’s no flags(283 Cars) & 409 emblems above flags located near the doors.
All 63 & 64 BelAir and Biscaynes had factory flags, V’s and 409 emblems with flags in front of tires on the fenders.
I made a written list all the factory locations of all emblems on all full size Chevrolet’s for 6 cylinder cars, 265, 283,327,348,& 409 cars from - 1955 to 1964 ( these engine emblems on factory Chevrolet’s continued into the later 60’s.
Many 6 cylinder cars had zero emblems on fenders, hoods or trunks were v-8 cars were on fenders, hoods, trunks and some lower rear 1/4s(1955)
“These emblems or lack of emblems “on original not changed cars (where the emblems have not been modified or removed)” confirmed the general type of factory motor each 1955 to 1964 Chevrolet came with”
