Ash - just pulled mine a few weeks back (1/70 k0) and luckily didn't chuck em...
I don't have verniers to hand so this is going by a steel rule / eye but is within 1mm ...
Overall length 43mm
Outer Diameter 26mm
Inner diameter 21mm
1mm 45deg chamfer on each end.
Hope that helps.
These are the phosphor bronze bushes I'll be using ... (Doing away with the phenolic top hat / felt washer)
