No longer need this, I had swapped it out, as the car was making a grinding noise. Turned out to be a front wheel bearing in the end and not the gearbox (the wheel bearing when first checked didn't show any signs of play and was not noisy when rotated by hand and it was only a few weeks later when it completely collapsed that I realised that it was the wheel bearing that was grinding and not the box), so as far as I am aware the box is fully functional. It has covered a lot of miles (160k), but the box was perfectly smooth in use, all gears engaged well and the car drove fine with it fitted, (ignoring the grinding noise caused by the wheel bearing). It also explains why I could feel no play in the driveshaft flanges or hear any nasty noises when turning the flanges by hand.
collection only from chipping norton as I don't have time to sort posting it at the mo. It is fairly compact, I picked up my replacement box using my mx5!

If it helps anyone I have a GT box here with a knackered 1st gear, one could combine the two boxes to make a perfect gt box? £8.46 and it's yours!
