This auction is for a factory installed 8-Track player bracket for 1969-70 Pontiac full size cars like Bonneville,Catalina,etc. The part number is 9796978.  This would be a good alernative to use for the Grand Prix or Firebird rear mounted tape player. I think the angle would be pretty close.  Buyer to pay 20.00 shipping and payment by PayPal or cash in person.  Thanks.
