Half cab for 74

[see ten]

I have a 74 blazer that I would like to convert to a half cab. I have went through pages of previous post ( all 16 currently) and the only links I can find to aftermarket tops don't seem to be working. I realize this wasn't a factory option but I think it would look good. I want the top to drop down behind the front seats and I was thinking about installing a pickup tailgate. I don't think I wan't anything permenant such as welding a pickup roof and back wall to it. Anybody have any pics or current links. I kind of want it to look like a short pickup.
