Seat belt buckle holders

[Man With A Gun]

I replaced the mandarin orange seat belts in my 77 Cheyenne with a new set of tan reproduction belts from LMC.

The new seat belts did not come with the plastic things that hold the buckle up so you can fasten it with one hand.

Anyone have a source for a pair of these? Bench seat, not buckets- I do see them available for bucket seats. Not sure if those would work with bench seats.
