Axle seal for 800/8000 G series?

Does anyone have the seal P/N for the rear axle seal on a 816. I'm getting ready to install the rear PTO axle block and the bad seal I'm replacing was a metal housing but I'm looking for the newer mostly rubber seal used on the newer G series. Also does the rear PTO shaft that goes in the axle block always have alot of play front to back. The axle block measures 4" and the shaft measured between the washers and retaining clips is 4.25" so the shaft can move 1/4" front to rear. Is that normal or is something missing or worn out? Thanks Jason

I bought a bunch of these recently from this seller:

This seal works for the 800s through the Pro-G's.

Now, for the rear PTO shaft. The original 816 just had a washer and retaining ring keeping it in place, and it moved like crazy. If you look at the IPL for a newer rear PTO kit, Gravely changed to shims and roller bearings. You should be able to use the later parts to lessen the slop, just beware that the exposed bearings are very susceptible to moisture. One of the rear PTO blocks I got recently was completely rusted in place, but it wasn't too bad to free up.
Thanks Marc I went ahead a got a couple of seals. now I see how the newer ones are put together. I was thinking the thrust bearings or bronze thrust washers 1" ID 1/8" thick they would take out the slop but not rust up like the thrust bearings.
I'm willing to bet Gravely didn't want that shaft to stay installed when it wasn't in use.
$8.95? That is robbery.
Teach a man to fish, I guess.

I have very little luck trying to cross any of these parts and I don't trust myself to try to measure them and risk wasting money ordering the generic part. The cheapest online Gravely dealer was $12.
