Sorry Tony & Keith, totally missed the threads on the light, thr bracket on mine has a single hole but they do look very similar, I thought it as an original fitting as the domed nut matched all the chassis rivet heads exactly, its only when I checked underneath that i saw was it was threaded, it shearded as soon as I took a spanner to it, the bracket, casing etc is solid but the bulb holder is toast so will need a new one fitting.
On a seperate note ref the assorted washers box, I bought 2 with washers, small nuts and bolts in seperate compartments to make life easy ...... and then tripped carrying both in the shed ...... ended up scooping them all up and putting in an ice cream box
