custom engine badges

[7gmc2]

last week i saw a 69 camaro with a custom engine badge on the front fender that read "383". it looked factory. not rigged at all. i thought this was neat, and wondered if anybody here knows if there is somebody makeing custom engine id fender badges? like the chrome block type that go under the side marker lights, with different cubic inch sizes on them, "402","427",ect....or the older crossedflag style emblems with newer engine numbers, ....i have looked for some but no luck i am suprised that i haven't seen anybody makeing these.. looking for "402" thanks
