Yes, in 1978, if you had the W72 Pontiac 400 the shaker had the "T/A 6.6" on the shaker. If you had the L78 Pontiac 400, or the Olds 403, then you got NO decals on the shaker. 1978 was a strange year. Also in 1978 there was no "Trans Am" decal on the front nose bumper. Another thing in 1978, the tail lights had no silver ring on them. It was black instead of silver.
