I have a 99 Lariat that the alternator crapped out on me on my way to work today. I know 95 was standard and 130 is an option. Is there any way to know what these had on them besides measuring the case body diameter? My truck is being towed home and I am at work so I don't have it in front of me. Just tryin to find out what I need. I plan on upgrading to the 130 amp if it has the 95 so I believe I will need a longer belt to make it work. Is there anything else I need to look out for? I want to pick up parts on my way home and make only one trip to the parts store.

 

blownpony306 i just replaces the 130 amp with a 95 amp but belt remains same because they both bolt on the same even though the 130 is bigger that doesnt change the center of the pully so it will work fine

 

Good point. I didn't think about that. Center is still going to be the center. So I should be good to go. Thanks!
