crossover tube o-rings

[walt460]

Finally, the correct O-Ring part number!

Ford part number is 391533-S100
LIST price is $3.67 each

Birdman941, thanks for the correct Ford part #. My local dealer here in Vegas area could not find the number, but your reference worked and I replaced all four Orings on the '03 Cobra I am repairing for a friend.

Does the " crack pipe" on the back of the head take the same oring as the crossover pipe?

No, it is a different size, we have them also.
