So this meant most suspension arms are easily interchangeable apart from the 1 or 2 (marginally longer or different damper connection)
The rear hubs aren't that different either. I kinda assumed any difference in driveshaft lengths would be down to the width of the diff.
Hopefully someone knowledgeable will be along shortly!
Sorry my bad... This is not the length of the sideshafs this is diameter of flange which connects to diff... Same is showed in realoem.
And it would be not logical if the length would be 86mm
So I guess everything is ok.
