I bought the injector and once I got it I compared it side-by-side with a Loyale injector. They're the exact same.
I vacuum sealed the injectors with desiccant packets. Hopefully they'll last until I need them. I've heard it's the moisture that'll corrode the coils and kill them.
Are you asking about that weird horseshoe gasket? For installation I use a few dabs of silicone grease to hold the gasket into the throttle body then quickly flip the throttle body onto the intake.
There's Walker brand throttle body gasket kits, I'd recommend those. You get every seal you'd need for a throttle body rebuild.
I'd recommend a coolant system pressure test after you install a new gasket. I've learned my lesson on that one the hard way.
