4 inch backing plate on a Griot's OP

[Mr 535i]

Is there an adapter to change the 6 inch backing plate to a 4 inch for paint correction?

I think the supplier you got it from carries a 4" adaptor .

Griots used to use the PC7424 , if its the same unit you can use :

I saw those, but the backing plate on mine is hold by 4 small screws instead a large one centered on the pad.
