Did rear seat belts not come in 1965 Verts? Mine only has fronts.

From what I've read over the years, only about 850 Chevelles left the factory with rear belts. 201 of them was the Z16. It was an option. Jan 65 was the mandate for front belts. Many dealerships installed rear belts, and our cars do have the placement dimples for drilling the holes.

I had to drill my own holes and it works fine.
