Hi Elvin.
First off, don't fit the eccentric rear poly bushes to an omega. They are for Carlton models or cars that don't have the rear track rod adjusters fitted. The track rod on omega relies on the softer rubber bushes to allow the track rid to pull the camber/toe over. If poly is fitted there is a very real chance the rear suspension will lock up.
Front wishbone rearward vertical bush, there are no official parts available to replace it. The only options are oe replacement items made of rubber from the likes of Gm, Lemforderor and Meyle who do a "heavy duty" version
Speaking of Meyle, I have spent a good while looking around for a suitable poly ball joint cross referenced with the sizes given on the Meyle web site for omega;
Meyle rear wishbone bush
614 035 0010
Height 46
Inner diameter 14
Outer diameter 49
Sadly no other vehicle I have found has a remotely similar sized bush. Much less one that is likely to have a poly version. Closest appears to be Corser C, but that has a 12mm inner diameter bolt hole, with no room to machine it out. Plus the outside diameter us way too big anyway. ...I wouldn't use a smaller bolt on a car this size either.
So that leaves some diy versions by members here.
These consist of solid lumps of Polly. While initial reports seem good, the sad fact is they are not a ball joint design, which is what the oe design is essentially, as it has to cope with an amount of yaw in the original design.
Basically the solid lump design stresses the metal work around the the bush, to the point that there has been case where the wishbone snapped.
Taxi Al has a similar design of black poly roll bar bushes from a ford Sierra cosworth machined to fit and sandwhiched end top and bottom.
I think Al would agree its not something that can be recommended to others with easy fit long term use in mind, due to stress in the metalwork, not to mention the restrictive movement making fitting the strut a challenge. Its a two man job.
But I'm sure he'll be along to comment.
The key to finding the front polys, was to cross reference the oe bush with other makes, and see if their is poly version for that vehicle. In the case of power flex they made a poly version for a BMW model of the same dimensions, m5 e42 iirc but I could be wrong. Hence they where then able to sell a version for the omega.
Sadly powerflex don't see enough sales in the omega to warrant a production run just yet. We are way down the list of profit making vehicles, as was found when we asked them to make a rear poly donut for us. They took measurements, but sales team dictate production runs and there's nothing for us yet.
However Taxi Al did find a poly rear donut by Pedders for the monaro that fits. So we don't need power flex now anyway.
My point is, though, sadly, that non of the oe bush makers web sites show an oe bush that cross references with any other vehicle with the same omega dimensions above, that I can see.
If you see one, or find one that fits, please god let us know.
