Hi DD,I don't remember which model Patrol as we where more interested in finding something on the Repco shelf quickly that we could make work in quick time as the car was sitting on the dyno.As it turned out we found a new unit from OEX with a part number of HXA070 and it made 90A,the mounting points on the bottom lined up the same as the A series(later model block in front of dissy)as did the top tensioner bracket,all I had to do was remove the new alternator pulley and replace it with the one from the old alternator so to run the normal V belt,seem to remember placing a 3mm washer behind the pulley to align the belt properly.
As far as manifolds are concirned,I fabricated everything in house as was unable to buy anything that would work off the shelf.
