. . .Just got home from work in one of the vans as my 320i is in bits all over the workshop floor.

Iregular chinking noise turned out to be fan on alternator hitting something. The rubber bush in the lower mounting has disolved, so it's twisting around and wearing away at the rad hose aswell. Seeing how the temp gauge don't work, i think ive caught this just in time.
My question is; can i buy this bush seperately? Do i remember seeing uprated ones on ebay? ('cos they're not there now). Could someone reassure me im not going to have to fork out for a whole bloody unit. . . .
Thanks.
