Rear Differential Pinion Seal Part Number?

[EddieC]

Having difficulty pinpointing rear differential pinion seal part number.
Using our VIN that gm parts sites bring up two part numbers without explanation.
RA comes up with many Delco parts, some identified by ring gear size but I don't know that information for our Tahoe so it's just confusing.
How to pick the correct one?

Not looking for a gasket.

Not seeing a pinion seal in that list.

See, searching on that site it list two seal numbers without explanation.

You might try vin on this site, if you look at one Pt# ending with 29 the assembly shows 10 bolt cover and one Pt# ending with 28 assembly shows 14 bolt.
