Does anyone know the size diameter of the swaybar on the 360GLT (B200) and if there any replacement bushes available for this?. Or any car that ran the same bushes?

IIRC its a 19mm Diameter.

Are the bushes the ones that are in the centre of the bar? the 'body' to sway bar ones? - Universal ones can be found in places like here (the '300 series' part is just a coincidence). Some companies do poly ones

Dai may do them on here too?

Otherwise if you mean the drop links found on older 360's that have rubber bushes, the whole links and polybushes are available from Dai

Thanks for the link. That's exactly what I was looking for
