You will notice both are FelPro, which is great, except...
One only gives you the pickup gasket and the Oil Pan Gasket. While the other gives you these things plus the Front Cover, Crank Seal, Water Pump, and more.
Do yourself a favor if rebuilding and don't be dumb like me and just look for the oil pan gasket kit that is OS30767R. Get Felpro CS9917, same price darn near. Just 2 more dollars.
