This is a pair set of wiper arms for the 63-64 USA built Full Size Chevy with single speed wiper motor.
*** THE USA built LHD cars... ... sweep from the LHS to the RHS.
*** The built cars by Holden in Australia & NZ.... RHD cars..from 58 sweep outward from the CENTER.. LH & RH..
We don't know if this is going to be OK for anybody with a Local Australian/ NZ built full size Impala, Belair, Parisienne or Laurentian to use ONE only and or twist the end of the pressed are the opposite direction .. better if you have RHD built car to TRY and find some RHD ones.
This is for a 63-64 LHD US Built cars as shown/ explained.
Below is the also available wiper blade arm half of each side.
