Has the 132 & Argenta limited slip diff or are they only one wheelers?
The early 132 had what we call a banjo diff centre, the whole centre pulled out from the front of the axle housing, they were the smaller 8 bolt CW&P, the later ones were salisbury, the centre was assembled in the axle housing via the rear plate, some were the small CW&P, and some were the larger 10 bolt CW&P. LSD was available on the later type, but very rare in OZ. The larger CW&P was Borg Warner I'm lead to believe, Fiat had 3 ratios, 10/41, 11/41 and 12/41, different ratios from other cars should be available also.
