3/4 Ton 4x4 Short(er) Bed Conversion?

I found a bed from an extended cab (a little longer than a true short bed) and I'm wondering if I can use it to shorten my K20 frame. I think the bed holes from the extended cab will mostly line up. See any issues? Thanks!

They are 18" shorter in front still a 6.5' bed.  All the standard holes will line up if you shorten the bed where the gas tank is.

Thanks!

So turns out that working by yourself can create barriers to bed removal. I had to rig a chain hoist from the roof rafters of the garage to raise and switch out the beds. Here it is for a test fit. It looks like I will need to remove about 17 inches from the frame.
