The Loyd parts book suggests part No: 78E-8575-A or 78-8575-B3. It does however say that you will only require 1 off,
bloody manuals!
The JobLot auto parts book that I use to order bits from the USA has 11A-8575-A as a 160DegF (71 DegC) unit and 11A-8575-BHT as a 180DegF (82 DegC) version. I guess the HT just implies 'High Temperature' version. I understand that the 71 DegC version was the 'factory' standard post war, but I don't know if there was a difference between the cars and trucks....
