Regardless of what he says, none of that has any direct connection to Ruddspeed. Yes they sold Konis, I bought some from them in the 60's, don't know about coil overs, they were usually fitted when you did a lot of towing. Konis were the popular, good choice.They also sold a carpet set but so did many other companies. Even if it showed the small numbered Ruddspeed plate riveted to the head on the flat just below plug #2, that wouldn't make it a "Ruddspeed" as they would sell the heads to anyone. That would give it a bit more street cred though.
I have a couple of pictures on the Ruddspeed site of their instrument panel and recently the Club 10 neck tie.
