All fiat puntos use electrical power steering
Very rarly u see a 1.2 8v with manual rack
The mimimum is 60amp on early versions
There were 65 and 70 amps versions too!!
As for physical differences on non ac setup is very little...
Need some pictures to see why yours dont fit...
As non ac use a 3 bolt slide to tension setup
Where a/c versions use a fixed 3 bolt setups and a automatic tensioner
