Detachable bed sides

[low4life1]

So, I remember seeing in the LMC Catalog that the bed sides and front panel unbolt and come off of the 67-72 pickups. But after looking closer at my 72 longbed that i was thinking of cutting into a short bed, it dosent appear that it comes apart that easily or at all without the help of a saw or my plasma cutter. It is a steel floor bed. Is it just the wood floor models that the sides unbolt and come off of? Thanks for the help in advance.
