Outer Limits 4x4 Board

Does anyone know where to get rear seats for a 98-03 model xtra cab? I've tried a few local wreckers (and some not so local ones) but no luck so far. Ive heard the older model seats don't fit. Is this true? If i can't get rear seats at a good price I'm thinking front bench might be an option. Will the single cab bench seat fit in an xtra cab? I havent tried a toyota stealership yet but my guess is their prices would be criminal. any thoughts?

I was looking at getting these for my lux. Worth a look on ebay.

Thats the way I was thinking of going. Just not sure if they fit. Toyota want $900 each for factory rear seats and thats before seat belts and compliance. the front bench is a lot easier to find. Anyone know if they will fit for sure?
