I love this site and all the helpful responses!!!!!!!! Another question, there is one knob on the dash I havent a clue what it is, If I was guessing maybe something connected to vents or heater. It is centered midway on the dash, on the bottom of the dash, pointing down. It doesent pull but it can be turned clockwise and counterclock. It looks to be original equipment. ........... Sounds like a riddle doesent it!!!!!!!!! Thanx! I'm sure this is just common sense to alot of people. but any help would be appreciated!
