Ive got two thudbuster elastomers new in their packets ready to fit if the yellow one gives up, how do you find them? I'll need to make a suitable spacer if I switch to them.
They aren't the originals but they're very very similar.
If you use the thudbusters you must short them until 2,2cm both them if i'm not in a mistake. I could measure an original bush that i have to be sure.
I drilled out the hole (the diameter of the hole must be about 1,1cm)
You can lube with a special grease and voilà.
