You can attempt to email but he's closed up shop a year or more ago and his stores closed down. There are lots of other people in the states making parts for Blasters that will actually send you parts.
I received the same story from him about orders held up by customs. That's his go-to statement. I've had him send an order a year after he said it was stuck in customs or the label fell off but that was 2 years ago before he started his new business venture. Lots of local guys have parts similar to what he was producing so there are better options in states now.
Side note but what's his new business
