That's how I found them. One album is on the banner now. The other is by searching. Mine came with spring installed into filter cavity almost hitting the big threaded post. We need to fix this info. Right now I don't know what is correct for mine. It is possible this could cause serious motor damage. Not sure. Someone please look in their 66-68+ repair manual and let us know ASAP.

I would say that the correct one is the one that you don't see the spring.
My reasoning is...
Oil flows into the housing, through the filter and out through the center of the unit. So the pressure releif valve needs to have the valve facing where the oil comes in, with the spring behind it, so that if the filter clogs for some reason the pressure pushes the valve open and allows the bypass.
The one you can see the spring suggests the valve is at the end of the spring, which means it is either open all the time or closed and the oil pressure won't push against it.
So the first link, the one that shows two housings, would be correct.

The upper passageway should be for the center, the oil going into the block, the lower passageway the oil coming from the oil pump. The bypass valve is in the end of the upper passageway.

If the pressure in the filter gets too high, the valve in the center of this should push and compress the spring, allowing oil to bypass the filter.

the valve portion goes up against the opening from the filter, with the spring behind it.
This is what makes sense...
