Kick start lever and assorted hardware can be sourced anywhere....many key pieces seem to be NLA......
Did you check here? http://www.mikesindianparts.com/COMING VINCENT PARTS.htm
Yup I have looked there...But does it look to you like most his parts are sold without a finish? I have not called, hell I do not have the bike yet so there is no point yet, but it looks like you get the part and then you get it chromed or nickel plated etc... I will figure this all out once I own the bike...I have since I wrote that post find just about all the bits I need I am sure it is just a matter of digging...Like I said once the bike is mine...
Cheers and thanks!
