WTB: Valve for REI inflatable pad (or pad w/ functioning valve)

[bcamprini]

I just picked up an REI inflatable pad for nearly free. It has a defective and falling out valve, but if I could find a new one and set it with some epoxy, this pad would be just like new. The problem is, REI doesn't sell the replacement valves (which are a slightly larger diameter than the Thermarest ones). If I can't find a REI pad to cannibalize, I'll just get a Thermarest valve kit and try to make it work, but I'd prefer to use the correct part.

Any dead REI pads out there?
