Looking online for transmission parts for my Civic R because the 2nd gear synchro set isn't available from Honda here. Found it from Japanese parts sellers and also noticed parts that ARE available here are so much more here than over there. Three examples:
Transmission fluid filter strainer.
U.S. retail $53:

Japan price $8:

Bearing.
U.S. retail $105:

Japan price $22:

Seal.
U.S. retail $18:

Japan price $5:

And yes, there is shipping costs from Japan, but that's less than the savings on just one bearing.
