Mopar Muscle Association UK

It's a long shot but I'm going to try just replacing the O rings on my axle seals before I fork out £90 for a pair of Green bearings.
Before I go to Bearing Man, are the any actual good quality ones out there?

I got mine from Frosts.
Is it an 8-3/4

It's a Ford 9" case but has Mopar ends.
I've looked at the case more closely and there's some surface corrosion just where the O-rings seat. The case stood empty for over a year before i built it so this must have crept from the weld.

Fingers crossed, that's my problem!
I'll try Frosts ta.
