Mission accomplished...
I was going to buy the U-Clamp online as it is usually cheaper, but it would not have arrived in time. Have you ever used Parrs Parts near the Rugby Stadium? They were very helpful, one of the guys there couldn't find the awkuardly sized clamp to start with and went though parts manuals to find it, then called me back to let me know he found it and ordered one in for me, which was £2.34 inc. VAT, so around the same price as online.

Hahahaha, I think this is called peer pressure . . . . .
