I have looked at many pictures on the internet trying to find these particular emblems installed on a car. The only ones I have seen on a third gen say "5 Liter H.O." with the spelling "Liter" and not "Litre" These don't even say "H.O."

It is a GM part and say they're for the rocker panels. Any input?

 

Those Are Most Likely For Another GM Vehicle,Not A Third Gen.

 

I bought them off Ebay. The seller lists them for a Camaro rocker panel and shows the part number on the box as #20359801.

My car isn't a "H.O." by any stretch, but I always felt that Chevrolet should've put some additional emblem on my model like how they did with the Berlinetta and other models on the left hand side of the bumper. I'll either install one on the back bumper or just keep them for future use.

 

Could they be badges used on Export cars in Europe/Canada?

US spells LIter, EU spells Litre.

 

Interesting. This source also lists them as being for third gen Camaro rockers and shows a blow apart picture diagram of them installed on a Camaro rocker

only place I've seen that decal spelled that way was on second generation Firebirds

 

Per the Parts and illustration catalog those are for a 82-84 f body emblem (BY1) and they go on the rocker panel
BY1 rpo code is ornamenttation , exterior emblem var 3

 

yes they are for an exported car.

 

Got the emblems today. I took this picture demonstrating their size in relation to a typical plastic picnic fork as I didnt have a ruler on hand.

 

"Litre" is French.
Rest of Europe spells "Liter".

 

Found a picture of the car model the emblems came on from Fav Cars.com: Z28-E

 

Look at the mirrors, it's an Canadian export version.
Explains "Litre", as parts of Canada are French speaking....
(Not many 3 Gens are exported to Europe, and only a very small amount would have been sold on the French market....).

 

We didn't get those mirrors up here in Canada (that I can remember).
