Real Jeepers don't whimper about the cold :-)
Right Bill ;-)
Everybody not familiar with Jeeps always ask me.
Is it cold in the winter? I guess because the
CJ5-7 soft tops had snaps and they WERE COLD
in the winter. Even my newer (at the time) 88YJ
soft top. Ok in the city, but as soon as you got
on the freeway, I hope you're wearing mitts,toque
and long johns.

The door for the duct is waaayyyy up under the dash in the center. It
has one cable to activate it with a second cable hooked to the vent door
on the passenger side.

The Olds engine had both the intake manifold heater and the carb
