8800 GTX Thermal Pads: Where to get replacements?

Well, after listening to some faulty advice on the internet I tried replacing the thermal pads on my 8800 GTX with AS5. Quite disastrously, the stock cooler does not even come close to touching the RAM and other bits... and generic thermal pads from computer stores are much too thin to bridge this gap.

Where can I go to get similar thermal pads to the ones Nvidia uses? I called eVGA for help, but the guy on the phone was of absolutely no help. Didn't know where to go (other than a "local computer store or something" ) and wasn't able to provide me with the stock stuff.

I really don't want to RMA the card just to get stupid thermal pads. In fact this may even just force me to go into water cooling, but I've already spent too much money building my current computer.

I really, really, really regret screwing around with my beloved card... please help me!

PS: No games or stress testing should be ok for my card right? Only the core IHS is making contact with the stock cooler right now

Haha, keep things stock? No way, my cars, guns, and computers never ever remain stock, and this is usually a good thing. I learned too late however, that messing around with the 8800 GTX generally is not a good thing.

I don't have the stock thermal pads that's why I am asking for where to get replacements.
