That sucks. But, those cranks fetch a good price. Maybe you'll even make money with spring approaching.
You need a crank that is compatible with any English Thread BB.
So if you're going with Red, you need one that has outboard bearing cups. Let me go look.....
I believe you'll be looking to get a GXP BB.

The cups will screw in to your frame, leaving you with outboard bearings. Then the drive-side crank arm will slip in. Attach the non-drive side and you're done.
