As stupid as it sounds, the mudflaps are a discontinued OEM option.
Also, I will be buying the OEM Bra and Nose mask from a friend of mine. Its leather and has the "civic" logo embroidered where the H emblem would be. It even has the cutouts for the OEM foglights...IF I EVER FIND ANOTHER SET!!
As far as I know, heres the list of OE options
Foglights
Bra and Nose Mask
Mudflaps
Rear Speaker Mounts
Center EQ console
Armrest
Honda CD player
Door Visors
Moonroof deflector
I think thats it.... at least for the Hatch
Id say the hardest to find out of all of those is a the fogs, with the bra at a close 2nd
