Both of my side mirrors are loose and will not stay in place. I am pretty sure the springs are just stretched. Do I need to buy 2 new mirrors or can I get replacement springs for them? I haven't been able to find them anywhere online so far. And if I do have to replace the mirrors what are some decent ones that arnt to expensive?

You may be SOL, no such thing as replacement springs for those. Either get new ones (shop around, don't go GM OE!), or scavenge a pair from a salvage yard.

The mirrors should be attached by two springs. One at the top of the mirror and one near the bottom. Make sure they have not broken loose from the cheap plastic mounts on the mirror base. My passenger side mirror has a busted lower spring mount and flops when I go to the car wash. I think I am just going to epoxy the mirror to the base and make it solid. If you find any good looking F1 or carbon mirrors please let me know.
