Which part of your 60/40 is damaged ?
Some of the seat have bolt on tracks, if yours do find another passenger seat and swap the tracks and you will have a set of 40/40 seats or bucket seats.
The backs need to come off first before swapping the tracks but there are holes on both side of the seat pan and the passenger seat will fit either side of the truck.
I used a set of seat that came out of a 98 Extended Cab in my Std CAb Steppie by turning a few bolts and time.
Other than that you can get the Explorer Seats as stated, The Explorer Sport seats are a little wider so if no center console is planed they are a little more comfortable. Mountaineer Seats are the same as the Explorer, then you can make mounts for anything as long as it will fit the cab..
