Shobud knee lever help please

[Hangdangdoody]

Hi folks,

Is there anyone out there who can help……….

I want to lower my 9th string down from D to C# using my RKR knee lever. The cross shaft is already in place for lowering the 2nd string sooo am I looking at fitting a crank, rod and nylon tuning adjuster, is there anyone out there who can help as I have no spare parts etc?

I’ve attached a photo of the undercarriage of my Shobud Pro 1 (well I think it’s a Pro 1). I bought it new from the Shobud shop at 25 Denmark Street, London around 1977.

Thanks
