I am in the process of replacing any controls on my dash ('78 cj7) that dont work properly. Ran across a problem. Can not see how to remove the top switch (fan control), so I can replace the switch mech. behind the panel. Anyone care to give me some advice?

I was able to remove the faulty vent-pull cables, but some knobs are different. I will also have to remove the wiper switch to get to the elect switch behind the panel. The light switch looks like it may also be a chore.

I did remove the tach. as it is a 6 cyl., and I need an 8cyl. Any pros or cons to the different "stock" brands being sold?

I am going to replace the clock with a vacuum gauge. Has anyone else done this? I need to find a vacuum gauge that looks similar to stock and fits a 2 5/8 inch hole. Any suggestions?
