SS/B Barracuda project

It seems there are a number of different wire separators on the Street Hemi, the ´65 Race Hemi and on the ´68 SS Engine.
On the Street Hemi of cause they came from the factory. On the SS-cars, may be, may be not...
I need to find a guy who know what a Big Block in a production car locks like from the factory, when it comes to spark plug wire retainers, and see if I can use one on them...
When I look at the left retainer, on the Street Hemi, may be this is the one. Flip it and lay it flat with separators facing upwards and bolt it on... Maybe this is how I do it, if no one stepp forward and tells it like it is.
