Oh, the irony.
Apparently, you should be expecting a PM from me with a picture of the GRENADED part. Aaaaaaaaaaaaaaaand, I was agreeing with pretty much everything Tom said.
Look, I don't care if you know more about cars than I do, but that doesn't give you any reason to direct that kind of attitude toward me.
And my "lack of knowledge" would not have allowed to to successfully rebuild a small engine. Now, not to sound like I know it all, but I figured out the cubic inches of it.
