I have 2/3's of what you need. I have the clamp and factory bolt, but not the factory lock washer. However, it is just a 1/4-20 bolt and I have a generic 1/4" lock washer, so it'll work fine. Email me your address and I'll get them in the mail.
Here's the one on Big Blue, and you can see why I need to pull the engine and replace the front seal, and the pic on the left is what I have for you.
