Anyone have this original in-bed spare tire carrier mounted?

[71CHEVYSHORTBED402]

I believe the bracket below was common for 67-72. Thing is, I happily threw mine away decades ago when I had visions of restoring my former bed HA!. Never did have the bolt or nut(s). Anyway, I believe these brackets were mounted between the LH cab and wheel well from factory.

Reason for the post:

1. I have a "new" bed. It's super duper, but lacks the screw holes for the carrier bracket. Can anyone offer a measurement for where that mounts to the bed? The carrier has to be vertical, so a measure or two should work fine. I checked the assembly manual for 10 minutes and did find one. It's a different carrier, possibly used where a gas tank is under the bed. Any volunteers to index the manual? Kidding. Bed...Bed.....Bed.......More bed

2. Picture(s) of the correct bolt and nut(s) to mount the wheel appreciated too, especially for a C-10 short bed. Here's the trick......Thanks to a board member there are "three bolts different sizes and lengths to match up to the vehicle".

Thank you
