Master Cylinder Pushrod Retainer Question

SeattleQQ1Fish said
Called Mancini and the person I talked to has never even heard of a groove in the cylinder bore to hold the pushrod in. I returned it and got what I needed from Napa, no problem. Another Mopar lesson learned.

Unfortunate Mancini's did not have the part/knowledge to serve you, and the wasted time, but glad to hear that NAPA put you back on track.
