'68 Z with cowl plenum
 

Neat car with what looks to be an original GM interior (I can't stand the look of the puffy repro door panels and seat covers with inconsistent seams, so I really notice the original stuff).

Is that a repop cowl plenum? The lid looks odd to me.

Air cleaner looks fiberglass.

The lid, body and duct all look like fiberglass.
