wtb 11x14 or 8x10 kodak 2-d bottom back holder hardware OR ZONE VI 8x10

these cameras don't use the pins but have ledges at the base to hold the gg backs--I want to convert my pin cameras to these for simplicity--so I want the bottom hardware for the 11x14 2d or the 8x10...I believe that will fit too, if they're not identical

Alternatively, if anybody has NOS zone vi top and bottom ledges and sliders for this (best system there is to attach a gg back) I want them, man.

long shot I know since these usually come with a camera/frame/etc....
