Seat belt length

Evening all,
I need to order a set of aftermarket seat belts for my Duster, w/bench seat.
Can you please measure the short piece that would be from floor to drivers right side?
It looks like most aftermarket belts come with either a 20" for bench seats (I'm thinking too long) or a 10" sleeved for bucket seats (which I'm thinking is too short).
If you have put a set in your A body with bench seat, how did it fit, and what co. did you go with?
Thanks,
C
