Top Box - need a few bits

[ben17484]

I've recently replaced the wing rack on my bike (altered to fit so the previous owner could use panniers) with a standard rack for just a back box.


As I already had the plate and the box I just ordered the rack and this is what i now have (sorry about the pic in the dark):

and I have one of these:







so I now need just the bits that connect the two. I can't seem to find these for sale separately and want to make sure that when I do buy them I'm buying the right ones.


Can anyone point me somewhere where I can get them?


Cheers,
Ben
