And the air filter on a DGV mounts a different direction.

OK, I haven't researched them, just repeating what the PO told me. I obviously have some homework to do, If they're not DGV's, what are they. Anyone recognize them? They came as extra parts with my 74 & are set up for a Z.

Do you have an idea of what you'd take for them? At the right price I'd take a risk on them.
