Retaining arms for a P3/Biostar motherboard?

Does anyone know of anywhere that sells the little retaining arms that help a processor attach to a motherboard? A consulting client bought a Biostar motherboard that didn't come with these arms, and the processor won't stay in the slot (since it's weighted down by the heatsink). Biostar doesn't have them available (the model has been discontinued), the local crappy PC parts store doesn't have anything like it, and it's far too late for my client to return the mobo. Anyone know of anyone who sells odd junk like this?

No idea. I usually resort to "manufacturing" something down at my workbench when I run into this kind of problem

Yeah, that's what I figured I'd end up doing. Just wondered if there was somewhere I could pick up $1 worth of plastic to save the customer $10 worth of labor.
