We can help you out on this obsolete part. This is the switch that operates your vacuum pot and has the capillary tube going into the evaporator core. The Interceptor's original switch works in a lever fashion and what we carry is rotary. The change is not a big deal I promise. Don't you hate it when someone says it's no big deal and you end up 40 hours later and having to hire someone to fabricate some 50 cents worth of steel for $150.00. Well, not this time.
