anyone that tried these (o) x-rings?
They are mend for the SC10 4x4 but amain says these fit the B4.1 too?
Since the B4.1 uses the same O-rings as the B4.2 I assume these fit the B4.2 too?

Would these be smoother? I though xrings were better than orings?
and maybe they seal better too? since the x rings make twice as much contact?
