Guys

Im having an issue melting my damned vacuum hoses that go to my wastegates. I'd like to convert them over to stainless steel lines.

Does anyone know the thread/pitch for the tops/sides of the tial 44mm wastegates?

This way, I'll go grab some earls adapters and rid myself of those pesky melty vacuum lines

10mm x 1.0 for all of them.

Stainless sounds like a good plan.
