Also I think that Dansk sells the SSI stainless steel aftermarket HEs for the -6 too, & they're just across the Channel, so check them & maybe get them before Brexit takes effect.
Stoddard may have a UK or Euro source you can use, or try the Porsche dealers in the UK too.
I'd suggest you try local UK/Euro sources to avoid paying tariffs in both directions + VAT if you can, unless it works out cheaper from Stoddards in the US.
Sierra Madre Collection out here in SoCal also sells the Dansk OEM steel HEs for the -6, but they're probably cheaper in the UK/Euro market without shipping them back to you from here - after they ship to Calif.
