Chris,

Obviously poor research on our rep's part. (I just spoke to her and
straightened her out.)  No, only a CA model would have an 02 sensor. We're
backordered on our usual supply of U.S. made aircooled Vanagon CAT's for a
week or two, so we bit the bullet and dropshipped you an OEM
Volkswagen/Canada one from the distributor. (I say 'bit the bullet' because
the one we sent you cost us as much as you paid for itl)  It should have
either had no hole for a sensor, or come with a plug to fill the hole if
there was one. (I've seen them both ways.)  In any case, as Kaye noted, we
have sent you a plug at no charge, which you should have in a couple of
days. Just to make sure you got the right one, the CAT you got should have a
flange on one end but not the other, and probably has a part number sticker
saying 043 131 701 E.  I checked and that is what we ordered, so unless the
distributor actually sent the wrong CAT entirely, you have the right unit
but it's just missing the plug that should have been included in the box.
