3D PRINTING CLASSIC CAR PARTS: CHASSIS THAT ARE COMING BACK, BUT THE TRIM ISN'T

The classics are getting resurrected; original Mustang, Bronco, and Datsun Z bodies rolling out — but you still can't find the dash pieces, vents, and trim that nobody's made in 40 years.

That's the gap nobody's talking about. And it's the one you can actually close yourself.

Here's the exact steps you'll need:

• Know that whole classic bodies are being remanufactured (and what parts are being left out)

• Learn which classic parts you can 3D print from your own garage

• Pick the right material so it survives a hot dashboard or engine bay

• Make the part that no longer exists

Let's get into it.

CAN YOU REALLY BUY A BRAND-NEW CLASSIC CAR BODY?

Overseas, a factory called Juncheng now builds brand-new bodies for the Datsun 240Z, the Toyota AE86, and the '67 Mustang.

A new 240Z shell starts around ~$9,500; the Mustang runs about ~$16,000. One of their reproduction Bronco bodies even sold at Barrett-Jackson for six figures.

Larry Chen partnered with Hagerty did a full tour of the Juncheng factory and the new chassis along with all the steel body parts look just like the originals.

But there’s a missing link when it comes to putting these classic cars together.

The plastic.

SO WHY CAN'T YOU FIND THE PLASTIC PARTS TO FILL IT?

After the chassis is assembled with all the stamped steel panels everything that bolts into it — the dash bezels, vent louvers, center consoles, interior clips, relay covers — its all missing. Your talking about 30+ year old parts.

And trying to find originals on eBay or Facebook Marketplace pulls a premium price tag.

If you find something cheap, the parts are usually cracked or sun-faded and still need tons of work to restore.

And aftermarket is completely non-existent.

That’s the gap where 3D printing earns its keep.

CAN YOU 3D PRINT CLASSIC CAR PARTS?

The good news is many interior, exterior, and even engine bay parts were originally made from plastic.

This makes 3d printing with similar high heat and UV resistant materials perfect.

We've designed and 3d printed hundreds of parts for our own classic BMW E30 and Datsun builds — gauge surrounds, delete plates, vent pieces, relay covers — parts that don't exist anywhere.

The only thing you can’t make from home are load-bearing or heat-critical components that typically aren’t made from plastic in the first place.

✅ PRINT THESE PARTS FROM YOUR GARAGE

Interior trim
Dash bezels, vents, switch housings, delete plates, door trim, etc.

Exterior trim
Mirror housings, plastic grille pieces, badge surrounds, hood scopes, fender flares, etc.

Functional non-structural
Brackets, clips, fluid caps, organizers, mounts, relay covers, etc.

WHAT MATERIAL HOLDS UP IN A CAR?

Short version: ASA for anything that sees sun or weather on the exterior of your car, because it resists UV without fading and handles up to 210° Fahrenheit.

For real strength or high heat resistance under the engine bay, Polycarbonate PC or a carbon-fiber-reinforced nylon like PA6-CF or PA12-CF are perfect.

💡 PRO TIP: Match the material to where the part lives. A dash piece in the wrong plastic warps the first hot afternoon your car sits in a lot. We break down 3d printed car part filament by temperature in our beginner's filament guide.

HOW DO YOU MAKE THE PART THAT'S GONE?

This is the real skill — and you typically have two paths.

1. If a rough model exists online, you can just send it off to your printer or you can even reverse-engineer it: measure your car and modify the file to fit.

2. If the car part doesn’t exist to download, you’ll need to design it from scratch — real measurements, use a 3d scan, sketch in CAD, exported print-ready.

Number two or even reverse engineering a design you found online is where most builders get stuck.

This is why I built a Design-to-print process. It’s made for builders instead of engineers.

The bodies are coming back. The trim isn't.
