Also,

Also, the front cover has a small crak in the shaft (which means the release bearing is sticking. I could weld it, but would prefere to get a new one. I've already purchased on, but it turned out to be the wrong one. mine has a smaller cut out for the bottom shaft, and shorter shaft..Again, anyone know where I can get one?.

Finally, does anyone know what this hole is for?....Do I need to block it (it's going into a rear wheel drive kit car)?:

Many thanks for any help...Paul.
