Steve, I believe you're going to find that the Ford engines of that era all used the same basic oil filter, the MotorCraft FL1A or equivalent from other suppliers, like WIX 51515 with ¾-16 thread and Gasket 2.834" O.D. & 2.462 I.D. I've seen spin on oil filters missing the flat rubber o-ring gasket that fits into a recessed ring on top of the filter unit, and on occasion have seen that gasket stick to the oil filter adapter on the block which means two gaskets - one stuck on the block adapter and one on the new filter, which doesn't work so good if it's not noticed.
