go to your local hardware store and look for allen key grub screws. take a sample from your pedal to make sure you get the proper size. you should be able to get about 15-20 for a whole lot cheaper than you would from calling Dan's Comp, paying the shipping, and waiting for them to arrive.
and pick up some Blue Loctite to use for the pedal pins when you install them. this way they won't vibrate out so easily next time.
I have some wellgos that I like a lot other than the fact that I lost about 5 of the pins after the first 2 rides on them. I found replacement grub screws at my local Ace Hardware.
