I have an '83 camper with A/C, in the rear, as usual.  Behind the A/C unit
there is a small shelf.

This shelf and A/C box are bolted onto the van in various places.  One
place is that on the left, it bolts to the closet.  The last time I took
stuff out of the rear, I noticed that this hole is missing a bolt.

Does anyone know what bolt goes there?  I tried to look in the ETKA but
didn't find this.

Thanks!
Wes
