The 150 is a Sequoia alternator. It is a bigger case and does require Bill's bracket.
Thanks for the info.
I am still puzzled to discover for which vehicle the people at Powermaster sourced the bigger case 170 amp alt from Denso USA that fit so well the FZJ engine as did on mine and doesn't require any bracket ?
As I explained before in another post I only needed to purchase a 80 series pulley, machine it's shaft diameter to fit the wider shaft of the replacement alt since the kit came with a round to inline plug adapter !!!!!
