Ever pulled apart a car interior and then stared at a pile of panels, wiring, and carpet wondering how it all goes back together? If you've got an NA Miata project sitting in your garage — or any classic car interior restore — that feeling of overwhelm is real. One wrong cut on your carpet and you own it. Forever. No going back.
Here's what nobody tells you before you start: the order of operations matters more than anything else. Install the carpet before you know where your speaker wires run and you're pulling it back up. Glue your sound deadener to the body before you realize there's a fuel pump access panel underneath and you're ripping it apart. These are the mistakes that turn a weekend project into a month-long frustration spiral.
Imagine instead finishing a Saturday with a freshly painted floor, sound deadener laid perfectly in place, new carpet tucked and trimmed cleanly around every bolt hole, the dash clicked in solid, the center console sitting flush, and the shifter knob threaded on just right. The kind of result that makes you stop and just look at it. That's what this checklist is designed to get you to.
The team at 1A Auto has walked through this exact process on a real NA Miata build — not a clean studio demo, but a genuine project car with missing bolts, mystery holes cut by previous owners, mice-chewed HVAC boxes, and wiring that needed cutting and splicing before the radio would even work. They've made the mistakes so you don't have to, and they've documented every step that actually matters.
This PDF checklist captures every actionable step from that build: vacuuming and prepping the bare floor, sanding and priming, painting, installing the HVAC blower motor and heater box, laying sound deadener without blocking access panels, gluing carpet to panels without gluing panels to the body, routing speaker wire before the carpet goes down, trimming carpet using installed bolts as guides, reconnecting dash cables, plugging in the glove box wiring, installing the shifter and boot, fitting the center console with Velcro carpet cover, and getting the seats back in. Every step is in sequence so you don't have to rewind a video fifteen times.
For $3.99, you get a clean, printable guide you can bring right into the garage. Stop second-guessing the order. Stop making costly cuts too early. Grab the checklist and get your interior done right.
Every checklist item comes with actionable notes to guide you — things like "Don't forget to do this before you start," "Avoid this common mistake," or "Set a reminder for 30 days out." Nothing vague, just clear next steps.
