Me, too. Since I've got a '91 with the big plastic speaker grilles I figured I would cut new panels out of fiberboard or lexan to look like the later door panels with a simple round hole for the speaker. I plan to recover in black vinyl with red nylon door pull straps a la Porsche RS.
You should do it, check my garage, I've done it to my 95, eliminated my armrests and plan on putting pull straps on when I can figure out what to use for them. I originally had these on my 97, the tops are from a 91 to get rid of that extra bolster on the back top edge of the door (only on 96-97). No armrests is roomier, and looks cool, until it's raining and you have to pull the door shut without the handle, the girlfriend hates it! lol. Next time I'd like to do it in metal with rivets.
