I believe the TS, and TB, ARB is attached to the lower a-arm, while newer 24v v6 have it attached to the damper/strut. The damper travels a longer distance, for a certain bounce movement, compared to half way in on the a-arm. This makes it possible to use a thinner ARB. When attached to the damper, there is no push/pull forces going trough the outer ball joint of the a-arm. This probably increases life length of this part as well.
The part are therefor not directly interchangeable, however the ARB´s are probably bent in a similar way to fit above the steering rack. Could also be a chance that an ARB for a 156 fits, as well as one from a Fiat Cupe?
Iäm planning on modifying the ARB on my TB, however i think that the end of the ARB is very close to the drive shaft, maybe making it impossible to mount ARB links going upwards there.
