finding jdm interior trim parts isn't always easy. try calling several different honda dealers both in your area and on the net, describe to them the part you're looking for, and see what they can do. sometimes you can get lucky and find the actual part number on enthusuast websites/forums specific to your vehicle. i found some australian sway bars and bushings for my camry that i never knew existed till someone mentioned them on a camry forum. maybe you can find something similar. with as many civic enthusiasts as there are out there, i bet you can just search some honda forums (honda-tech comes to mind) and maybe find the part you're looking for, or at least the part number. then the trick is finding a local dealer that can actually order the part for you since it's probably not going to be in an american warehouse.
btw - silencery - what mag is this gonna be in? i noticed you said "draft".
also, i am the one who asked about the screen being up that high on the dash, and glare/washout in a convertible. i know you have a hardtop, but now that the weather has warmed up, have you taken the top off? if so, how does the screen look on a bright day with the top down?
