The facia you identified as HJ... is this because of high beam indicator? I notice it has the block off for the wiper switch that should be used in HJ.

Could you do a list with pictures to identify each model and the differences, one day please, as Im sure a lot of people get these wrong.

I still have original one out of my HZ sandman with only file marks in radio hole, (similar to the bottom one in your pic) just waiting/hoping to find the rest of it that I sold in 90s

cheers
