So difficult to measure in-situ ! I didn’t want to pull a wheel out to check things, but I have some bits set aside for the next rebuild, and a bare frame. The brake plate retaining/centralising nut is 0.792″ overall length, including the rounded end that goes into the dish around the hole in the brake plate. The bare frame is 7.75″ between the axle slots. I wasn’t able to measure the components on the sprocket side of the wheel as I don’t have any floating around in the workshop. I hope this helps !
