Morris to Marina disc conversion

The Morris I bought for parts for this project had a tuned 1275 engine and disc brakes. I assumed the previous owner had down the work and I only had to use the bits. Unfortunately, the person had just put the Marina hub with Marina bearings onto the Minor axle. Then tightened the nut to prevent the loose fitting bearings wobbling. 

So what I was expecting to be a hub conversion was nothing more than a bodge. Consequently I had to get the conversion, which proved not much better that the solution without it.
The whole experience is described here .
