Glen:  I'll be watching this one carefully.  My 60 Bugeye has the
identical problem, but is bone stock. (note to Soave: I know its
supposed to have a rubber mat!)  Its hot here in central Florida and
Ive bout given up driving the car for the  summer.  An additional
quirk of mine is I have to stay below 50 mph.  As soon as I push it,
the temp build up is rapid.  I dont now how far it would go as I back
off at about 205 degrees.  Let us know if the sleeve made a
difference.  Larry
