Please forgive my denseness, having never done this before. When removing the outer timing case cover, what happens to the contact breaker assembly (points, condenser, back plate)? Which is the case: 1. I should remove the assembly first, OR: 2. The timing side outer cover comes away complete with the contact breaker assembly, OR: 3. The timing side outer cover slides over the assembly leaving it in place as it comes off? OR: 4. None of the above, and I am even more dense than I thought? Thanks for your patience. Phil
