Taper roller swing arm conversion

I have some pictures, PM me if you want them emailed to you. I have no dimensional data or bearing numbers as I have never used the scheme but saw the photo's on a forum and copied them. 

Even have a swingarm here, swapped back to the MK3 original items. 

Email sent with pics attached, Philip.

Think there were Norton specialists who performed something similar on Slimline (and probably Wideline- are the swingarms the same?), as wasn't this something available for later Manxes?

I'm a bit out of my depth on this topic, but would be interested to know if this is still feasible?

... what the advantage would be over a good condition well lubricated original setup?

another way to spend unnecessary money. Stock set up is fine when in good nick, and maintained !
