Sorry for digging up an old post, but I was in a similar situation and thought I'd share what I found. From the picture you posted, it looks like you need bolts 02199 and 02199Q for the flywheel cover. I did some searching online and found a great site called scrooz.com.au that has a wide selection of bolts and fasteners. I've used them before, and they're really reliable.
I'm actually pretty new to this forum and haven't had a chance to contribute much yet, but I wanted to share my experience in case it helps you out. It can be frustrating trying to track down the right parts for a project, but it's always a great feeling when you finally find what you need.
