I put a Longacre in mine. I think I'll put my stock mirror back on and buy the clip on mirror from Western Auto for $10. I have the two mirrors from my FV I'm planning to replace the stock flags with. I have trucker convex mirrors stuck to my flags at this point, I don't like them. A car close by my rear fender looks like it's clearly behind me, but since I know where he is it isn't a big deal. But it's just one more thing to think about. I don't really use the rear view mirror too much, I got by fine in FV with only side mirrors, but it is nice to actually see who and how many cars are drafting you.
