Outer Limits 4x4 Board

Hey how's it going my name is Eric I just came back from Austrilia and I loved it (I'm from Canada) I want to look into getting a Toyota Dual Cab truck 89-95 body style. It only needs to be the cab with doors and interior I'm going to build a custom frame. I was wondering were would be a good place to look and how much do you think they go for Aprox?

Cheers.
