Votex Bike Rack

I have the standard 4 bike rack made by Votex, does anybody know where to buy the frame stay required to hold the 4th bike in place? My local Van Centre cannot find any reference to it on their system. I also need a couple of extra wheel straps.

Try banwy for the stay. We sell the straps here.http://vwcaliforniaclub.com/shop/product/replacement-strap-genuine-vw-t5-bike-rack

Thanks Calikev, I have bought new straps from yourselves. I am just wondering if I could borrow a 3a connector from another member. I am reluctant to spend £58 to buy one for a one-off trip.
