Just go to your bike shop with it in your hand and tell them you need two of these :wink: I actually don't know what they are called

im might just have to try this tommorow. i was going to try normal bolts, but the studs (what ive been calling them) are tappered, not flat.

What you have is referred to as a "Cottered Crank". The items you describe, Cotter Pins, come in a variety of sizes. Overall length, diameter, and "pitch" of the flat part are all factors. By all means, have these items in hand when you go to your local bike shop. There are MANY different sizes!
