Camshaft + Crankshaft Position Sensor O-Ring

[SailorJerry91]

I'm planning on replacing the O Rings for the crank and cam position sensors. However, I can't seem to find the correct size, nor the part number.

Does anyone have the correct info to order them?

Engine: LM7 5.3L

If you pull them, replace the entire part. Believe you need to do a relearn with a scanner or a 1/2 to 1 hour road trip with starts, stops, in town cruising and highway.

The reason I said a relearn or a road trip, is that I have seen/heard where both will work or one of them will not work. But, it can also be the person doing the work.
