At the U-pull yard ANY alternator is $25, I was looking for at least a 120 amp but then saw this one, Googled the part number on my Android and found it was a 146 amp!!! Sweet, just had to use a bigger fuse and wires. I used a mini ANL fuse I had in the parts bin in the line to the battery. I rated it as just a little over the maximum rating of the alternator just in case it starts to over charge...
