SS/B Barracuda project

Well I first saw this photo from early ´68 of Bill Bagshaw´s Dart a couple of years ago, and it is a good sours for my project. It was recently also posted by 66340SEDAN some where on this Forum. Thank You...
Anyways... like I said this may just be a retainer taken from a BB or SB, thus painted...
As for the other thing that dosen´t look like as delivered, the car has been in the possession of Mr. Bagshaw for a week, two or three, what do I know, but we know all kinds of modifications and preparations was done for the track as soon as it came to their shop.
As for the wire separator, may it be the typ that is pressed on to the retainer?
Now lets see if anyone can recognize the retainer and the wire separator from another late sixties engine...
