I think it is 180.00 more but if you want the fj-80 tre's you have to send them your pitman arm first and tell them you want the fj-80's, for the 20.00 to bore the pitman arm it seams well worth it.
You can do that, but you don't have too.
That is an option. FJ TRE's are huge compared to Samurai ends.
If you go with the complete OTT steering it uses FJ ends for everything except the pitman arm. That is replaced with a new Suzuki end.
It is nice to be able to adjust you steering with the new Toyota ends. They are a Left and a Right hand thread. You don't have to take things apart when making adjustments. Just loosen the jamb nut and rotate the tube to lengthen or shorten.
I didn't send anything in. I am using a Tracker pitman arm on mine. I have a 16 valve with power steering in my zuk.
