I've install a 100 amp alternator out of a Nissan patrol gu. With the only modifications need to be done it remove the clutch pulley which any good auto electrician can do and you may need to hack saw the battery post down because it may hit on the engine mount. Depending on what size belt u run

 

Also you will need to make a small jump wire out of a piece of 3 or 4mm wire with a push terminal on one end and another terminal to go to the battery post. The push terminal goes to the source terminal in the plug.mark "S"

 

Also don't forget to plug the existing single plug in tho the illumination terminal in the alternator plug marked "I".

Have you got any photos man?

 

I'm interested to see what this looks like! :y:
