Getting classic car parts remade
When the part went out of production decades ago, a maker can often remake interior trim, knobs, clips and small brackets from your worn original.
Post your part — free Posting is free. You pay only if you accept a maker's quote.

Restorers know the problem: the car is complete except for one cracked knob, a missing trim clip or a broken window-winder handle that nobody has made for decades. Reproduction suppliers cover the popular models; for everything else, the original is often the only reference.
Manufacturers face the same problem. Porsche Classic, which looks after a range of some 52,000 parts, began 3D printing very rare parts where making tooling for small batches is inefficient, including a clutch release lever for the 959, of which only 292 were built (Porsche, February 2018). Mercedes-Benz Classic prints genuine parts such as sliding-sunroof rollers for older saloons, because the process suits small quantities when the original tools no longer exist (November 2018).
Parts makers commonly remake
- Dashboard, heater and radio knobs, and switch caps
- Window-winder and door handles (interior, non-structural)
- Interior trim clips, escutcheons, bezels and grommets
- Badges and emblems for your own car (see the note on trade marks)
- Glovebox catches, ashtray and courtesy-light housings
- Small brackets and spacers for trim and accessories
- Seat and trim fasteners for non-structural parts
- Tool-kit holders and storage clips
Materials and processes
Resin printing
Fine detail for knobs, badges and bezels; the maker finishes and paints to match.
ASA
Heat- and UV-resistant interior and exterior trim (Prusa: up to 93 °C).
Machined brass or aluminium
Turned knobs, bushes and spacers where the original was metal.
Moulding and casting
Some makers copy a part in silicone and cast it in resin when several copies are needed.
Don't have these remade
- Brakes, steering, suspension and wheel parts
- Seat-belt mounts and anything holding a seat
- Fuel-system parts
- Exhaust-side and engine-bay parts near high heat
- Lights and lenses that must meet road-legal standards
Buy certified originals for these and have them fitted by a qualified person. The safety page explains why.
Try these first
- Check the marque's own classic parts service and the main reproduction suppliers.
- Ask the owners' club: clubs often commission small batches of hard-to-find parts.
- Search autojumbles, breakers and used-parts listings with the original part number.
If nobody sells the part at a sensible price, a maker is the next step.
Good to know
Logos and badges can be protected by trade marks even on old cars. Making a badge for your own car is common, but selling copies is a different matter, and makers may ask about it. Check the rules where you live.
Send the best surviving original you have. For a pair (left and right), say whether the maker should mirror one.
What to put in your post
- Make, model, year and chassis number, and the original part number if known.
- The colour and finish to match (a photo next to a colour card helps).
- Whether you need one, a pair or a club batch.
- Photos from every side with a ruler in shot, and the measurements that matter. The measuring guide shows how.
Step by step: find the model number, measure the part and photograph it for a quote.
