Sprint Sprint ST 955 Panniers

I am new here so have probably posted this in the wrong place.

I want to get some side bars that will allow me to mount my Kappa one key panniers on my bike but the item I need is discontinued (KTF.11.267.100) that's a Motech PN. I have the panniers for another bike and I don't want to buy another set so I wonder if any one has any suggestions as to where I can get the bits either new or second hand.

Thanks for any help on this one.

 

managed, after a lot of messing about to find a SW Motech one that was for my bike a dealer in liverpool had one - the last one
