Disco 200tdi timing cover

Changing the cambelt on my 200tdi disco and some bolts ont he water pump sheared off in the timing cover. Trying to remove them, i've cracked the timing cover, right where the water channel is! Wheres the best place to find a replacement timing belt cover... i've tried fleabay and can't see any.

use chemical metal or one off the breakers in back of LRO

It's ok folks, found one on fleabay eventually. Came with what looks like a nearly new water pump too! So i'll stick it on and hopefully thats that job done.
