<VV> Rear-seat-back Latch

[N. Joseph Potts]

In 1968, a positive latch was introduced to hold the back of the folding
back seat up. It went on the right side only. I've been querying vendors for
this item, and have been told they don't have any.
     Would anybody on the list happen to have one they'd be willing to sell?
Expensively? (Yes, I really want one.)
     Failing this, would anyone know of a substitute (e.g., some other
Chevy/GM part, or even a generic gate latch that has been found suitable)?
The part numbers are:

68 striker	7773917
69 striker	8745525
68-69 lock	7779669

They're in Group 11.620.

Thanks.
