Friendly confession: while I am in there may be the most expensive phrase in the garage. A clean build is strongest when the visual decision also respects fitment, serviceability, and real-world use.
The habit that finally stuck was simple: mock up the change before final finishing.
Haha, “while I’m in there” really can turn into a much bigger project! Mocking things up first is definitely a good way to catch fitment issues before spending more time and money.
