Quick question kzn185 surfs

[ian and jean]

Hi quick question can anyone with a kzn185 and rear wind deflector measure the width for us ....ours measures 73cm....but been told acompatible set for a kzn185 is 66.5cm if everyone else measures the lower measurement. .I am confused at what we have...trying desperately to get a rear deflector ....thank you..

I have a KZN185 on the driveway but I'll be honest I have no idea what a rear wind deflector is?
