A HA! I found my old thread. Here is the details:
The plugs under the floorpans are two sizes... small and large ones.
The part numbers are as follows (from GM)
Large Plug Part # 1021-5806
Small Plug Part # 2057 9955
I even have some pics of the new plugs... they came with the rubber "gaskets" on them, and just snap into the floorpan. I only had one that was starting to get rusty, so I only replaced one so far. Figure I will only replace them as needed, but bought a complete set to have on hand. I think for the six of them it was $20 or $25 with tax. Not all that expensive.
Also, no guarantees they are still available, but its worth a shot.
