3 10mm bolts and 3 8mm bolts. It sucks getting to the bolts behind the pump as opposed to the front exposed ones, but it's still doable without jacking up the engine, let alone dropping the k-member or removing the engine entirely.
What have you tried other than oil weight to fix the chatter though? Does it happen at a certain rpm? under a certain amount of load? Have you tried putting seafoam in the oil? I've seen it fix the problem a few times. But if it's a collapsed lifter then it'll need replacing. I really would find it hard to believe that the oil pump is the culprit, especially if you've driven it for a year with this problem and not destroyed the motor yet. I would suggest removing the upper intake, lower intake, and valve covers and replacing your lifters, because like I said, I honestly doubt the oil pump is the problem.
