Wall trough fittings

Morning all, we have a pair of metal wall troughs both 30" long that we had on our old house but unfortunately we did not bring the bolts they were attached to with us as we thought we'll get replacements easily enough. It turns out we made a mistake and despite searching many hardware stores in person and online we haven't found them. I've attached a photograph of something very similar however the gap is not wide enough for the trough to slip into. Any suggestions as to where we might find a selection of these?

 

What size do you actually want? Which gap in your photographis too small, the mouth of the hook or between the hook and nut?
Also a sketch showing how the trough and the hook go together might be helpful.

 

Can you not modify it?

 

I had a browse and Greenlion66 is right....it seems impossible to buy the fixings separately. Should think the best option would be sturdy, long all-purpose wall screws and rawl plugs with a suitable length left proud of the wall, and hook the baskets over with additional wiring to secure. Failing that, perhaps UK DIY outlets sell heavy-duty hooks? Whichever, rawl plugs would be a good idea!

 

Can you modify/cut these to perform ?;
