selling bumper ducts for 90-91 and also have them for the 92-93 ntegra not pictured price is 65 shipped buyer pays the fee if anyone has any questions email at jjfrozo1989@aim.com
those are 90-91.
92-93 are more curved so they wont fit.
You should post some pics of the back and info on the dimensions of the back of the duct. In order for these to be useful people will need to attach brake or intake duct hoses. Looks good so far though.
Yeah sorry it was a typo and the backs are 1 1/2 and there about 3 inches tall so they fit with the bumper support I’m working on another version that is not painted
