Need Bearing Seal Part Number for 2000 30' Excella

Can anyone provide the part number for the OEM seals on my 2000 30' Excella? I've got a quick trip coming up (---family reunion) - departing this Wednesday - and I would like to repack the bearings and check the brakes before departure. I thought for sure that I had a spare set but I guess I used them the last time I repacked the bearings - and neglected to replace them. Further, I can't find where I wrote down the part number - so I'm 100% sol. I'm a long ways from the nearest Airstream dealer - but I'm hoping that one of the large RV facilities within about 35 miles of here will have the seals. I hate to pull a wheel to check the part number and then find that the nearest seals are several days away.

I just order 4 seals from Dexter Axel last week. They are Part Number K71-305-00. They come with two seals in a package and cost 13.24 for the pair.

Hope this helps.

Look at this site
Dexter Axle - Trailer Axles and Running Gear Components - Seals

Once you find the size any auto parts store should stock them.

If your current seals are double lip try and replace them with double lip seals. The new stuff is single seal and if used will allow the axle to rust in beyond where the out lip of a double would seat. Once single seals are used doubles will not last long if used.

The correct number turns out to be National 412920. Airstream's number is 630370-100 - but they don't offer any cross-reference - and the mother ship (Jackson Center) no longer ships parts. All they do is refer you to the nearest AS dealer. Strange enough, my local parts shop was able to get the seals - but they had to call on three other regional shops to come up with four seals! It seems like each shop only had one seal apiece. Further, with respect to the mother ship, the last set of seals they shipped to me had both CR and National seals in the set - and the part number on the National seals was the "generic" 412920. The Airstream part number was nowhere to be found. It makes me think "customer service" is failing somewhat. Oh, for the record, I paid $19.00 each for the seals.
