Longbed to Shortbed conversion

[70blazer]

I just pulled the bed off of the 67 longbed I was given last week. The kid behind me started to pull the truck apart and his dad got sick of it sitting in his garage so he came over and told me I could have it. I have not been on the board much since I had my back fused back in 11/03. I had to sell my 69 to pay for medical bills. I am sooooooooo excited to have picked up this truck for nothing. To get to the point, the bed is very rough. I would love to have a 67 short fleet so how difficult is it to mount up a short fleet bed on a longbed frame?

Anyone done it successfully? I would love some real info. on this before I decide what to do and you all have been incredible to help me out before. Thanks in advance and here are a couple of shots of what I got done today.
