[Gmcnet] Wall bolt locations for davo needed

[Larry Engelbrecht]

My floorplan didn't come with a davo but I'm converting it to that. The GMC parts coach I got the davo out of had a piece of aluminum welded to one of the vertical ribs. This piece and a rib itself are drilled and tapped for what appeared to be either 1/4 or 5/16 bolts, 2 per side, to support the hinge for the backrest/upper bunk part. I have a piece of angle aluminum I'm going to bolt to the rib.

I measured this when I took it out of the parts coach and I wrote the dimensions down but misplaced them. Can anyone provide dimensions or a photo that references how high the bolt holes are? Thanks.
