i have found in several catalogs a factory option dash compass listed for 73-80 . it has gm on the front of it. does anyone know exactly where these where installed ? the one im looking at is in the chevy truck version of the "truck shop" catalog. it is also available in the lmc catalog for those interested. for those of you who have noticed i am interested in acquiring quite a few of the factory options that my truck either does not have or is missing. thanks and i hope this helps others also. darrenolander galva,il. 1979chevycheyenneblazer 350/350 gettin'down on all fours, 4 a'little x4 play !
