“My CX model Plusfour was modified at the beginning of October 2022 with the approved kit (new swill bin and new master cylinder both with ancillary parts all supplied by the Morgan Motor Company (MMC).
Did you mean swirl pot rather than swill bin?
In seriousness, I hope the rad fix works for you and you get to enjoy your CX.
