Netwrks1,
I just got back from Vaction, sorry, I wasn't able to reply back to you earlier. The URL I sent you is 3rd party from Curt Mfg. it WILL sit under the bumper and will NOT be flush like you wanted. However, the unit the Civic Ferio is offering looks like it will do the TRICK!!!
Wish I had this link three (4) months ago, before I bought my Curt!!!
No worries though, I've gotten used to my "UNDER" the bumper hitch, and it makes the GX look move "sporty"...
