Micky1Mo - I hope you can encourage Chris to sign up and post more details.
As it certainly looks like a lot of extra fabrication work went into the build.
There is a '49 Chevy over on 'Rods 'n' Sods' with a similar tail light set up.
Hopefully the Sammio's lights are less slightly to be bumped/broken where they are fitted.
Cheers, Paul.
PS
Closing the Sammio website seems to have "killed" some of the photo links.
