caddy tail light question

[55metalmonkey]

I've seen an image of 89-93 caddy tail lights frenched into the rear stake pockets on a TF truck, but can't seem to find any image of it done. I google searched it and searched the forum and still can't find it, I know it's been done
I'm contemplating doing it on my truck but would like to see what it looks like before I start gathering parts to do it.

Any help finding a pic would be great

Thanks
