Rebuilding a Manual Steering Box, Cant find the bearings seals locally! HELP!

I was looking on RockAuto.com for steering box seals & found a few listings, but the application info on some of them doesn't specify whether it's for a manual or power steering box. Can anybody tell me if these numbers are for a manual steering box? I couldn't find any contact info Rock Auto on their site so I couldn't ask them.

Gates part # 350510 (Steering Gear Complete Rebuild Kit/Bearings, Seals & O-rings) $37.79

Edelmann part # 7895 (Steering Gear Major Seal Kit) $25.79

They also list the worm shaft seal (#7214) seperately for $6.67.


Another question. If I have a damaged case with good internals is there any reason the parts can't just swapped straight over into another case?
