I'm planning on taking it by a body shop to get the minor hail damage that I experienced a couple weeks ago fixed. While I'm there, I'll see if I can get an estimate on how much it would cost to replace the mirrors. Your truck is exactly how I want mine to look, down to the tires. I've seen a couple of 2500s ECSB with the plain mirrors, makes me sad that mine got the "dumbo mirrors" option.
On a side note, today I 'uglied' the truck up a little bit. By that, I mean that I put on an alternate set of tires that have a little bit more tread and I swung the towing mirrors in. The new set of tires are 245s and the previous set were 265s. They're sitting on stock rims and the rim on the passenger side is a little dinged up from serving as the spare for about a year. As soon as I get some extra cash I'd like to get a new set mounted onto the aftermarket rims that used to be on my truck. I'll try and get some pics the next time I leave campus.
