For Sale: Original GM emissions control valve. This one came directly off my '68 400HO (4 speed manual). Completely untouched, even includes 50 years of light rust. (pictures show a green stripe hose attached that is unrelated but would be included). A small spatter of blue engine paint on rear of cap could likely clean off. Looking for $350. Also selling the original radiator from the same car. Core is shot, but frame seems good; could be cleaned up and re-painted.

'68 400HO Coupe, 4 spd, 259 interior, Windward Blue. My other car's a Johnson 15 outboard on a '61 Starcraft rowboat... Just sayin'.
