I own a FJ62 and like the power train. Still feels like a truck from that time period. Possible might do this myself but to a FJ45LP-B where length will not be a issue. Another problem not mentioned is you loose the hand brake with this setup. Adding the disc hand brake option will shorten a already too short rear drive line. I will go post 8/80 rear axle to solve this.Why would you ever want to do this.....?
