Hey Lee, I'm not trying to dissuade you, but . . . as you know, heater channels quite often rot from the INSIDE to the outside.
What looks great on the outside might still be paper thin! That stands true even here in California. Any more, when someone tells me "It's Rust-free", by default I figure that they do not know where to look for rust.
Unlike other patch sections, heater channels cannot be inspected without dissecting them.
Just food for thought before you pay someone to extract a pair of "rust-free" channels and having them shipped.
