well it's not so much the stuff on top, because I did the same thing and covered that with the floor mats. The holes i'm talking about are the ones that are more in front that are a few square inches for the bolts that hold the buckets in. Those I can't seem to cover up with the mats while still covering everything else, and they're real obvious if you're looking down into the car. I've been thinking of doing some cheap lightweight carpet in the summer time when i'm back from college anyway, so I think i'll just leave it slightly ghetto looking until then and cover the holes with the new carpeting.
btw, very nice work ssick. Are you doing custom carpeting over that or putting the stock back in? I'd love to see pics all said and done if you don't mind
