'02 F350 Dana60 axle rebuild questions

[Abitibi]

Hey guys,

I bought not long ago a set of front and rear Dana60/Sterling 10.5 (4.10) that came off a 2002 F350 SRW.

I started rebuilding them this week, all gears are good, bearings looked and felt ok and all seals were gone.

I'll replace the bearings anyway but where's the best place to get all 6 seals (including hubs seals)?
RockAuto Auto Parts, Ford dealers?..
And anybody got the parts#?

Any suggestion on the rebuild will be appreciated.

Cheers
Mr. D
