Hi Phil, in the finish they diagnosed that it was a buckle end fault and so I just changed the pair of those. The price they quoted for the complete belt got me interested and when I rang to order the chap talked through the problem and diagnosed a buckle release problem, as I was unhappy the way my hip was rubbing the buckle and damaging the transmission tunnel leather anyway he suggested a longer buckle stalk to move the buckle up above the tunnel when fastened, he even said if by some chance it's not the buckle and you want to change the rest of the belt they would adjust the price, he was THAT helpful. Can't remember the chaps name but he was so helpful.
