This is a complete unit removed from a full size 66 Pontiac. I know it fits 66 full size or Beaumont and if I'm correct it's also the right one for 67 Beaumont. I bought it thinking I might use it but I don't even seem to drive my cars in the summer, never mind work on them so it will likely sit on the shelf for years if I don't sell it...
Tested on a battery, both low and high speed work. Three studs retain it to the rear deck. They are all intact but I only have 2 of the 3 nuts that go on the studs.
Asking $95 plus actual shipping cost. I checked on ebay and a switch only, no defroster unit sold recently for $79 US so I'm thinking that must not be too far off for price?
