27 or 30 Spline?

I'm about to order parts to re-gear my diffs, so I figured I'd order some axle tube seals for my D30, but I don't know if I have 27 or 30 spline axles. I searched but didn't find any help. How can I tell which spline axles I have in my stock D30?
Also, any opinions on Ten Factory vs Alloy USA seals?

If you are talking about the tube seals that go into the ends of the axle tubes, they are a complete and total waste of money.

The only clue you have when you have a failed inner seal is when you see the oil running out the axle tube. There is enough volume on the long side that you can pump fluid into it and drop the oil level in the diff far enough to take out the pinion bearings and you have no idea it was happening.

I will say that the look on owner's faces when I explain that and then pull the long side axle tube and they see a quart of gear oil run out is fairly priceless, because up until that point I was getting the "Yeah Right" treatment.

I make it a habit to pull every set when I'm doing any work that involves removing the axle shafts.

That and if the seals are over greased, they collect dirt and start wearing a groove in the axle shaft which really isn't that special.
