stopped by after work and finally got around to fixing up my doorcards and speaker grills. Rivets and nice hardware > zipties. Back when I ordered the door cards last year, the company shipped me the wrong hardware. Took awhile, but I finally got everything (and tons of spares) from ‘em.
Press fit apparently. I probably should have drilled out the door holes slightly, but instead I used a pair of needle nose pliers to roll the edges back enough to hammer the fittings in.
