My ignition switch is pretty loose. I have the rear wire connections on tight, but the 'inner body' that houses the electrical connections is not tight in the housing. If I bump the rear while opening or closing the hood vent it tends to shut off the ignition. What are the suggestions for rebuilding or having the ignition switch rebuilt? I believe the exterior
"thumb switch" is specific only to the 47-48 models?
Thanks
