Yes they are the Spax adjustables.
I removed my trailer mudguard for clarity, set the engine at 2500rpm with the aid of a long brush which can be seen in the video. It didn't take long before the BB was quite hot at the input end although remained reasonably quiet. A stethoscope on the casing suggested it was no more noisier than the gearbox.
I had just re-filled the BB with 450ml of Millers EP140.
My next modification is to fabricate an NACA duct into the removable section of the floor pan so cold air from under the car will be directed up and over the nose of the BB.
Photos to follow in due course.
