Yep, U6 Electric Clock. Was sold to a priest originally (No not Judas! Lol). “Our Lady of the Lake”. Current owner said he swapped clock out as Brad guessed. Posi too!
I met the original owner of a 1970 Skylark vert with a 3 on the tree at a car show in Clearwater in Feb 2019. He said the car was a "factory mistake". He also had the car's "Mimi Me". UticaGeoff
There is a Catholic Church near my home here in TN that is also called Our lady of the Lake but I don't think any of the staff there had a cool 3-on-the-tree '72 Buick convertible. I have an old Chevy truck with a 3-on-the-tree and when I dropped it off to have some tires installed a couple years ago they had me pull it into the service bay because none of the tires tech felt comfortable trying to drive it.
My 72 Skylark Convertible "3 on the Tree" came with 3.08 gears.... I swapped to posi 3.42 gears and converted to a 4 speed.... pedals and odometer are still original.
