Seatbelt location on a '66

[stingray660]

Greetings to all

Can anyone help me on the location of the outer seatbelt bolts
near the cab corners. When the new sheet metal was replaced, I
failed to measure and locate where they go on the new metal. It is
a 66 fleetside, but I'm pretty sure they're mostly the same on 64 & 65.
Thanks Ray

If you need measurements from a specific point, let me know.
