I put one in when I had my 89 with the 2.6.It was a 110 amp I believe , but it wasn't cheap.It cost me just over 300 CAN , but it bolted right in.The only thing I had to change was the bottom bolt that threadedinto the alt bracket was replaced with a regular nut and bolt.No big deal to change.You might have to go back about 2 years or so in my posts to get more specs on it like name and part #.I do know its in there somewhere in posts on alternator upgrades.It worked alot better than the stock , especialy if you have a winch , or even just a few lights and a big stereo <img src="/forums/images/graemlins/smile.gif" alt="" />
