Fuel tank

I have to Daytona one just put back together and another going back together. The 53 plate has rubber mounts that push into the back off the tank so you can bolt it down. The yellow one is an 04 but the rubber mounts aren't there I can't get them from world of triumph but there are two tanks to choose from on there site. Is there another method of attaching tank with out said mounts or anyone know where they can be brought? Part 6 and 7 in first picture
