Heater ”backdate” – the $ 15 alternative
Edit #2: Don't bother with Aircraft Spruce for the sceet tubing. Just do a Google search on "sceet" and you'll find someone cheaper. I found a race shop selling it as NACA tubing, I want to say that 10 feet was something like $65, and that's enough for 2 cars.
