A few nights ago I accidentally "neutral dropped" when setting off from green lights and snapped my passenger side drive shaft. In pushing the car into a parking space, with the steering on full lock, the broken drive shaft got caught on the autobox and punctured a hole in the the outside cover plate! Now I happened to have a spare drive shaft so fixed that but am left with a hole in my gearbox. See the picture. I have put a wanted add up for a new or second hand cover. But pre-empting a hard to find part, do you think it would be safe to weld a patch over it? I am planning an oil and filter change as I may have got some bits of metal into the box. http://i.imgur.com/JGVPr0x.jpg
