I’ve been on FABO for a few years but I also have a 66 Belvedere II. It’s a 4 door with a 273, 904 trans, and 2.91 gears. It’s a great cruiser. It was my first car as a kid. I remember my dad bought it for $500. Drove it daily for about a decade until I got a more modern car. I heard so many stories back then of the “old guys” regretting all the cars they sold that I could never let go of this one.
