Bonded bush Girling 64541161
Bonded rubber bush (Girling 64541161) used at swinging arm/suspension and lamp mounting points on Triumphs from the 1978-1980 catalog era.
This is the bonded rubber bush listed under 99-7004, tied to Girling number 64541161 in our records. It shows up in the swinging arm and rear suspension unit fittings, which is where a bush like this typically does its work — taking up the mounting point between the swinging arm and frame or suspension unit eye and letting a bit of rubber absorb vibration instead of metal wearing on metal.

The part also turns up in our catalog against the headlamp and flasher lamp figures, so it appears the same bonded bush was used in more than one spot on the bike. Catalog appearances run 1978 to 1980, though we'd rather not guess beyond that on exact model fitment.
If you're replacing one of these, check the physical size and bore against what's coming out of your bike before you order — a bonded bush that's perished or cracked can let the swinging arm move around more than it should, so it's worth inspecting the old one closely.
