looks great! makes me want to get one

i mentioned this a few times, but if anyone's interested, you can make your own gasket to close up that gap using black hard felt. most art stores carry it, or you can buy them online. the one i use, product name is EZ Felt.

you can use a sharp knife and a ruler to cut the hard felt to size. ive been using this product for over 10-15yrs. :D i have no gap on my HU install with factory trim.

also a good idea to completely remove the thin gasket on the factory trim around the HU opening while you're doing the work. you can remove the adhesive using motor spray.
