Be careful putting later model seats in an older standard cab truck. If you are average height or taller, you may not have much room. The cabs on newer trucks are larger inside, so the seats can be larger and recline, etc. A highback bucket in a square standard cab is asking to be too close to the steering wheel unless the seatback is in it's full upright (uncomfortable) position. It's not as big of a deal in a crew or super cab, but it'll still get tight. I'm sure you've seen pictures of those trucks with newer seats and almost no space between the front and back seats right?
