Gameboy Color Battery Spring Replacement

Hi All,

I recently bought a pretty beat up GBC on the cheap. I intend to do a case swap so I wasn't particularly concerned with the condition of the GBC when I bought it, however the battery springs are pretty warped and my replacement shell does not provide new contacts. Does anyone have the replacement part number for these? I've found these springs on eBay http://www.ebay.com/itm/311099231126 and I'm tempted to buy them to give it a shot. I see that someone is selling original GBC contacts that have been pulled from other units, however at that price point I could take another chance on the eBay roulette wheel and get another GBC.

Thanks
