Silver or yellow?
is it 4mm? I see a 1.6mm and a 4mm stainless washer on Belmetric. Is there a correct source?thick washer underneath
Yeah that’s why I’m going with the satin stainless, the zinc just burns off over time in the engine compartmentZinc ones go to hell so quickly
My car also had that combo when I got iti have seen pics of @ccr2002 's very original 3.0cs ... and it had silver zinc domed nuts with thin washers.
