I wouldn't have thought so, but its not possible to check on EPER as they are not listed as seperate part by Alfa!
How much different are they? Is length different or hole position different?
ePer shows the wishbones as 60627604 LH or 60627605 right hand for a M7 (V6 Spider 2001->2003) but also shows others for earlier versions e.g. M1,2,3,4,5,6 = 60612317/18
ePer shows no replacements for 60627604 and does not list it as a replacement for 60612317
I'm not sure of the exact differences with the ball joints - my local garage is doing the work
After replacing all bushes, with new ball joints the camber was 3 degrees out (think it should be 1 degree) and back looked like this /---\
They have put the old ball joints back on, camber is slightly beter, but still wrong and definately would wear inside of tyres - which was exactly what was happening before they replaced the bushes
I may be way out, but my latest theory is that a previous owner replaced the top wishbones, but with an earlier part number, which is shorter ?????
The other theory is that the car has lowering springs, according to other threads causes irregular tyre wear.
Next step is to compare measurements with my "spare parts" V6 Spider!!
