Well I have removed my rear shock to get to the lower bushing, lets say there is nothing left of the plastic feeling bushing except the inner metal tube. so I measured the ring on the shock where the bushing goes it measures 22mm inside diameter the metal tube has dimensions of 16mm outside diameter and an inside diameter of 11mm
So I went to the
www.nolathane.com.au and used there bush size search link on the left hand side of the page to find something similar.
what I found was a couple of parts that fit part numbers 45144, (suits ford falcon XK XL XM OR XP MODELS for the front double control arm.) dimensions [23.5 mmOD 16 mmID 26 mmL 3 mmFLANGE
the other part # 47265 suits Nissan commercial patrol g60 [dimensions of bush 22.5 mmOD 16 mmID 32.8 mmL 4.8 mmFLANGE
So even though they are not perfect fits I think they could be made to fit easly enough
I will see if i can buy some of them tomorrow. and see if they fit.
I will also check the upper bushing on the shock aswell.
