Could see if FLM would make an aluminum bulk set to take the LST diff.
Have the support collar in it too.

see my question?

thanks

I dont think he had to do anything as such- at most a little filing for clearance incase they are tight ( like rpm arms tend to be sometimes ), but nothing 'special' which requires loads of work or special treatment. Just buy some and have a fiddle, you'll soon workout if anything needs doing.
