Holy crap!! If they're able to pull those prices out of an M20, then I've got about $50k worth of Muncies!!!

Seriously though, he should have gone with Italian gears (they're far superior), and laid of the pipe while doing up the ad. 

Check out Riverside Gear from Michigan. They have complete rebuilt units (M20) that have warranty for $600 cheaper. Plus for an extra $800 you could buy an M23 Super Case transmission. They have TONS of stuff.
