Craig, you'll be thrilled to learn that you can buy parts right here on this site, click on fastlane - I got a replacement for $7 if I remember right and it was Bosch brand!!
Sorry I can't remember how many screws, Carl. It was pretty easy on the right side, you may want to open up that side and take a look perhaps it would be more accessible and let you see how the driver's side is attached. I do remember there are some locator pins that fit pretty tight; you may need to pull harder.
RIP "Betsy" (Oo=*=oO)
