I have just installed a pair of the new axles, thanks to Stevo and Rik at Ross Mods for the tips and help. The new Factory Team axles are top quality and they are only slightly more expensive than the non Factory Team version.
Machining the end of the driveshaft is fairly straight forward and only requires a minimal amount of material to be removed to get the full articulation and rotate smoothly.
There is a noticable increase in the steering lock and more to come if I file (or dremel) away a tiny amount of the wishbone where the steering stop meets it.
Unfortunately the weather here isn't ideal for testing the new set-up, hopefully it will dry up sufficiently before the end of the week.
