[CA7638]

Hi I was hoping some informed soul out there could tell me where I can get a nice stainless steel/aluminium rear license/number plate holder for my 74 GTV.
I remember seeing one for sale on someone's website a few months ago but I simply cannot remember where.
I have a ugly moulded black plastic bracket and I wanted to replace it with something a little more elegant.............

Any ideas?

Thanks
Steven
