My alternator is going bad it needs to be replaced. The thing is all the auto stores I go to say they don't make a bigger then a 105 for my truck(95 1500 silvy w/5.7). I want to run atleast a 130 amp as I'm going to run Duals for winch and lights. Was looking at wrangler but I think 400-$500+ is quite a bit. Am I wrong? Is there other GOOD alt. not so expensive?
