Should have the car back on the road at the weekend after having to have my replacement diff rebuilt as it had gone noisy after only 150 miles. I can highly recommend Bara Motorsport at Bromsgrove. Although they normally only do full rebuilds Bara agreed to check the diff whilst I was there and decide what was needed to be done. It needed new pinion bearings, shim, collapsible spacer, and new castle nut. He also swapped the ring and pinion for a replacement that I had. Left it with him and collected it next day. Good fast service!
