Hoping someone might be able to advise. Having just replaced the rear wiper arm & blade (all standard, but a bit more of a bugger than I was anticipating!), I thought I would replace the front blades too. I presumed they would be standard, but they aren’t. Has anyone seen these before (photo attached), and know what they are? The blade appears to attach to a central metal slug in the middle of the attachment, which then pushes onto the arm from the end. Grateful for any advice[GALLERY=][GALLERY=][GALLERY=][GALLERY=][/GALLERY][/GALLERY][/GALLERY][/GALLERY]
