The wiper switch on my 65 tends to slip forward, turning on the wipers. The prior owners solution was to stick a small piece of cardboard between the wiper and washer switchs to hold the wiper switch in the off position. While this does the trick most of the time I'd like something a bit more permanent.

When I dropped the clock-cluster to examine things all of the pieces seem to be in place, but it looks like the "teeth" on the switch housing might be worn.

1. is this a common problem
2. is there a quick solution
3. are the switch mechanisms available new anywhere or do I need to look for a used part (I didn't see the part in the Thunderbird HQ catalog)

Thanks!
