Where to buy Final Drive Seals for 1967-20?? big twins?

[jas67]

MG Cycle has two different seals to replace the big seal, but, do not the smaller one or pinion seal.

Where is a good place to buy them?

This is for a 1977 Le Mans if it matters.

Harper's (harpermoto.com) and AF1 Racing (af1racing.com) should both have them.

There is no pinion seal.

I prefer the Viton big seal:

but the much less costly one works well too, maybe just not as long.
