Where to buy a brass bush for the spindle shaft on the drum?

We recently replaced the belt on our Indesit tumble dryer, unfortunately it had already done damge by breaking the spindle and brass bush on the back of the machine. We have repaired the spindle from a kit but the cuff/bush part wasn't incl so we simply turned it round and bodged it! Worked great for 4 weeks but with it's weakness has now broken beyond repair.
Where on earth can we get another brass bush bit from? Or does anyone know of an alternative 'thing' we can use??
The machine isn't a yr old and with 4 kids it's not something I'd like to live without.
Machine is an Indesit
Thanks in advance
