go to ebay and type in 200 amp alternators, there is a company that sells them and if you click on any of there auctions, go to the bottom and you will see the part for their website, they have alt. for any vehicle, they are a direct factory replacement as well, i am getting one for my system when i am done makeing in, i believe they are $250
my alt. crapped out in 2 years! luckily i had another stocker laying around so i had my guy rebuild it. cost me $250 but it puts out 240amps. he said at idle it is 180amps! so when i do the new motor this is going in unless the stocker craps out! then i will have that one rebuilt the same way!
