while the ones posted by TR-Spider look like some sort of adaptation.
these were actually pictures of the 124 Spider Abarth, which uses a different type of connection between lower arm and damperstrut.
The 124 was the "firstborn" Abarth rear suspension.
On the 124 Abarth you adjust toe by shims between the 2 lower outside bolts,
while on the 131 Abarth a separate adjustable rod is used to adjust toe
(The wheelcarrier parts on the 131Abarth look exactly as in the Lancia Montecarlo rear axle...)
