Bushes are readily available via cherished suppliers
I'm planning to replace my brake drums with the Tony Betts cast iron versions as my pressed examples are so badly oval they can induce motion sickness on long descents.
Can't find an appropriate emoticon (need a green one!).

Hope you wasn't after girling brake drums?
I might as well let people know, the casting company we were useing for cast iron. Has now gone bankrupt. Probably because they were half price we could get anywere else.
The cheif foundryman tried to make sure everyone got there patterns back.
We got everything apart from GIRLING BRAKE DRUMS.
The sad result of all this is due to there being very small profits in these parts, it's unlikely to be worth producing another pattern. The last one cost use £1,000 for a full pattern 15 years ago.
on top of this, the extra we are likely to have to pay another foundry for casting, may make the pre-girling drums unviable to produce in the future. ( I don't think people will pay what it costs to make them).
Now don't all rush
But I have 40 of the pre-girling cast iron drums on the shelf. The price is £90 each to cover the fact that we had 10 from this batch that have porosity, so I can't sell to public.I will look to see what future costs will be, but at the moment I fear the future of new brake drums is not good.
Sorry about the bad news, Tony.
