2nd Gen Dodge Ram floorpan help

[three60fish]

I'm working on combating the rust in my beast since I just don't have the money to look at another one right now. Repaired the passenger side with some patches, but the drivers side is beyond just patching. The floor pan has pretty much disconnected itself from the rocker and the rust hole stretches from the front of the door frame to about where your ass sits...not good.

That being said, I ordered the rocker, cab corner for the extended cab since that's what i have and it was bad too, and the floor pan. The guy at LMC truck said it wouldn't work with an extended cab truck, but I thought it couldn't be that far off and would be better than starting from scratch....well they came today and apparantly I was wrong. It seems that the floorpan is only from the hump to about halfway under the drivers seat???? who the fuck needs that piece, every truck rusts form the rocker in, not the hump out, right?

So now I'm looking for advice on what to do??? Does anyone know where I can get a full or at least the outer half of the floor pan for this truck? (1994 Ram 2500 extended cab). I really don't want to try to cobble this thing together as its prett far gone, but I don't know what else to do. I've searched and searched and can't seem to find this part
