I do not think that there is "correct" Ignitor II for a 41-62 Chevrolet 216/235/261 engine. The original PerTronix Ignitor is available for 41-62 Chevrolet and 39-62 GMC engines (6 and 12v volt; positive and negative ground).

$89.95

Make sure you get the right part number to match your style of your distributor.
