I made some calls today and found a yard with a 2004 with grey leather seats, they would not tell me the price until they knew exactly what parts I needed, went all the way there (about 50 miles one way) to find out the dude wanted $250.00 per seat

, not to mention they were sitting on a liberty with no doors outside for God knows how long, they were mold infested and the metal underneath was all rusted, I asked the guy to work on the price, he said " they will clean up really nice" (my as$... mold and rust is not something you can clean), turn around and walked away.
On the good side, I learned that the 2004 seats will work and that all I need is the diaphragm that goes under the seat, I can retrofit that and then go to the stealer to calibrate.
Now I'm looking for a cheap passenger seat for a 04, 05 or 06 (I guess they all fit).
Thank you Sir Sam. I'll keep posting my progress on this ordeal...
Ya I guess 04 seats still have the diaphragm so all you need to do is install your occupant sensor into it. (the 04 has the diaphragm but is of a different aesthetic style so it doesn't show on an interchange which slipped my mind yesterday).
I had forgotten about what retmil posted about install the diaphragm into an older seat, in that case just get the cheapest 04-07 passenger seat you can find, and install the diaphragm into your existing passenger seat as retmil showed, then connect up your existing occupant sensor.
