This is a 1968-69 Corvette Smog Diverter Valve. RARE Very nicely restored part with show quality finish. Part # 7029298. T-FITTING ON TOP. We do them in batches of 8-10 diverters once a year. here is a few of them. CORRECT FOR all 1969 427 Corvettes, note: the Tri-power cars had a special adapter plate to flip it upside down to clear the front carb.
