1966 Monaco 2-door - practically nothing on fecebook right now.
There's one for sale in Orange Cove California (on fecebook), it's a project, $3150 but I bet would take less (listed 4 days ago).
There's a 1966 Polara 2-door in excellent condition in Wainwright Alberta for $8000 (CAD) about $5700 USA.
There are several convertibles and maybe a dozen 4-door cars.
Outside of FB there's one listed at $32,900 at a dealer in Latrobe PA, another one in Blaine Washington for $39k. There was one on BAT in 2019 that was bid to $7750 but didn't sell (I wonder where that one is now).
FCBO member @The Furrrry One (Calgary) also posted a want-ad last year for a '66 2-dr Monaco.
Ok kijiji there's one for sale in Landmark Manitoba (near Winnipeg) for 4K cad, it doesn't look bad but will need interior R&R and probably paint job. It has a 318 auto and like all Canadian 1966 Monaco/Polara it has Fury dashboard. It has bucket seats / console and floor shift.
