Unlike other jokesters, this stuff is for sale for real.
Side covers, $50 shipped. US
Oil pan $40 shipped. US
I would charge even less for these, but shipping from my town seems to be expensive. Add a bit more if you're outside the US.
All the little stuff is sold together, $30 for the lot. Odds and ends include axle, battery strap, frame neck covers, rubber mounts, some bolts, perch (I think brake side), wheel bearings, rear I believe, rear wheel spacer, and everything else in the picture besides the oil pan and side covers.
If I find anything else laying around the garage, like spare ohleens or bread loaves, I'll throw those in, too.
