Just got a kit from Speedy fasteners via ebay. Only thing I had to do was very slightly enlarge the two holes either side in the frame for the bigger fittings, just a quick 2 second blip with a stepper drill bit did the trick very easy and doesn't effect reverting back to the standard fixings if wanting too, no modifications needed to the plastics. They do several kits in black or stainless, i went with the 18 piece black set.. heres a link https://www.ebay.co.uk/itm/17484685...NQJ6BY&hash=item28b5af58ad:g:REwAAOSwwL1m-9vh
