After careful measuring and calculating I mounted an Oak 1x4 on the wall, then went to ACE Hardware and picked up some Crawford U-shaped padded hooks that screw in to mount. They are similar but not quite identical to these I found listed on the ACE website:
The ones I have are more of a hard foam padding than vinyl, but you might see what you can find. Vinyl and the foam would be a no-no for a nitro finished neck, as they're likely to discolor the neck. I couldn't see spending $15 or more per mounting device.
The result...and note that the U-hooks can be rotated a few degrees when mounting Fender necks to allow for the offset cut on the g string side...
