Transporting a '67-72 bed on an '83 bed

[magillmagill]

Howdy! I'm stuck and hoping some of you have relevant experience.... I want to move a '68 bed with my daily driver; an '83 K20. Both are 8' beds. I plan to put the '68 bed upsidedown on top of my daily driver's, run wood 'indexing pins' in each stake pocket and strap it down. I'd simply get all the measurements but the '68 bed is currently an hour away. Anyone done this combination before? Are the beds the same width? Will the stake pockets line up at all? Kindest Regards...
