hinge pocket rebuild question - 1957

[hotrodsbyray]

well, i gotta do something about the lower hinge pocket areas of my truck. if i rebuild them - does anybody have a thread or site i can go to see how it is done?
i also thought about replacing the hinges with street rod style hidden hinges. truckin magazine had a series of build articles on a 57 truck with corvette innards. they used hidden hinges somehow aligned so they could use the original truck's door pockets. i cannot find a copy of that one months articles showing how they did that.
anyway - if anybody can throw me some help i'd appreciate it.
