okay for the seat belt, you can directly unbolt it from your current seats.
very easy be carefully doing this becuase that long black shaft part says explosive

. anways once you get your brackets you might need to bend the tip just a little on the part that inserts into the bracket so you can get a tight fit.
I just bent it slightly on the cement than torque it in. note: nothing fits like it should with aftermarket parts ever!
just make sure bracket says universal or you can order a pair through tenzo. They are extremely cheap.
Like I said remember only four bolts and 2 plugs in removing the seat.
Remove plugs under the seat first. They can be reused with your buckets so your SRS light doesnt go on.
