Help Needed - 1968 Camaro Convertible Top

[LesUK]

Can anyone help please. I am in the UK and I have been restoring a '68 Camaro for the last twelve years (well it was in a bad state!). After being ripped off by three different motor shops, I've finally found someone who has nearly finished the project. The problem is that they are unable to reassemble the convertible top frame and associated folding mechanisms. I'm sure all the parts are there but we have no diagram to refer to. We do have an assembly manual but this does not cover the installation of the springs,frame, rain channel etc. Bear in mind that the whole car was stripped to bare shell. Can anyone provide or let me know where I can obtain an exploded view diagram of the convertible top. It is manual not power assisted. Any help would be greatly appreciated.
