[stroker87]

hey guys I got a friend with a 95 silverado he needs to replace the alt & power steering pump bracket any of you know the size the bolts are? I tried to look on mine but cant see them and its a tight clearance so I though maybe one of you guys can make a life a little easier if you know the size of the bolts that hold it to the block?

Should be a 13 or 15mm.
