So this weekend I noticed my alternator front bearing started making noise. Additionally I had some charging issues, which I am blaming on my starter solenoid, but I figure just to be safe I might need to replace the alternator. Looking on Oreilly's website the stock alternator appears to be around a 70 amp alternator, seems kind of small for a full size truck.....

Are there any super secret swaps for this that I should look into, or should I just go get a stock replacement? Anyone know of a bolt in that goes a bit higher?
