Thanks Jono which one would you recommend going on your experience of maybe using them or seeing them? It might be easier than me trying to visualise them or judge the correct one by looking on the site.
Want one for my bench seat at the back which is a standard one from humber which opens up.
Also want one or 2? to lock my double jockey seat,the top just lifts off and maybe lock the 2nd jockey seat which has the internal fuel tank under it.
Are they attached by drilling a hole and using a screw and a nut inside?
