Motion cars rear end cover

[Yann]

Hi, just bought a vintage finned rear end cover for my Chevelle. I would like to know if there was a sticker on the cover on motion cars. If yes, was it was. Saw some with E-T decal on them, but mostly they dont have one.

Also, for motion cars that had torque thrusts, do they had MP decals on the center caps or the standart american racing ones? Ive seen both.

Thanks for your help
