Engine's Done (Sorta). Couple of left over parts!!!

This has to be a 1 or 2 year thing with the 71 or 72 Lesabre's and Rivs that have the trunk vents? plus your 73 GS has these too?
It was brought up on someones Lesabre thread I think..I under the impression it's a air ventilation system.. How cool that your Grandpa gave you the car and fixing the issue with the switch. Learning something everyday here!

 

Looking good. I remember when my chrome shorty headers looked that good. I have no clue how to get them shiny again without removing them!
