1981-86 Chevy CK Exhaust Manifold GM 0633 3 LH Left Original Used

As found, not cleaned. This is an original manifold, not an overseas repop.

See photos for details.

From what I can find, this manifold fits 1981-1986 CK series trucks with 305 or 350 engine and air injection (holes could be plugged for non-AIR applications). It may fit more applications. Please do your own research.
