1970- 1972 Chevrolet Chevelle/ El Camino/ Monte Carlo Used Non- A/C Heater Control Assembly #3979705.  Removed from my 72 El Camino in 1989 and stored  inside.  Chrome knobs and slide openings look good.  Lens has some minor scuffing.  Black paper insert has wrinkles (see pictures).  All three slides and 3- speed fan  switch work smoothly.  Fan switch untested but worked when removed in 1989.  Overall good condition.
