i saw some of the 6th gen accord gauges mods were successful but mine didn't go well. i got the parts from procarparts.com and i went to 2 installers, they both told me the faces were too thick and the centers were too small so the needles won't run smoothly. the 2nd installer even cut out the center edge of the tachometer face, which was a really bad job. i finally got my money back for both parts and labor cuz they didn't tell me anything before they did the cut, that thing looked extremely crappy...i don't know if it's just the parts was bad or it wasn't just me....if you have the same parts installed please share your experience. thanks a million!
