So I found this lying in one of the back seat pockets of my Williams 3.
Rubbish camera phone photo - but it's a metal tube sprayed black, approximately 300mm long and 2mm thick with 11mm holes in each end. It has apparently cracked at the square end and then been re-welded and filed down. Looks like some kind of supporting bracket?
Does anybody know what is it? Do I need it?
