When the Parts Catalogue Ends

Every classic vehicle eventually crosses the line where the manufacturer's parts supply stops. Specialist suppliers cover the popular models — but if your vehicle is rarer, or the part is one nobody remakes, the restoration stalls on a single component.

We close that gap: send the original part — worn, broken or corroded — and we reproduce it. For parts that are missing entirely, we can often work from the mating components or period photographs. See how automotive reverse engineering works, or a worked example: a discontinued Peugeot 406 anti-roll bar bearing clamp (5172.41) reproduced with no dimensions.

Custom automotive replacement parts precision machined by EKINSUN — brackets, hubs and bushings for classic cars
OEM-equivalent automotive parts machined from billet in our Guangdong facility. Brackets, hub flanges, bushings and threaded fittings — all reproduced from the original part, no drawing required.

Parts We Reproduce

Mounting brackets

Engine, gearbox, ancillary and body brackets in steel or aluminium.

Bushings & mounts

Suspension bushings, engine mounts — machined PU, bronze or rubber-cast.

Hub components

Hub flanges, wheel spacers, bearing carriers to press-fit tolerance.

Machined fittings

Carburettor adapters, manifold flanges, cooling system fittings.

Trim hardware

Window winders, latch mechanisms, badge bases, interior fittings.

Motorcycle parts

Frame brackets, footpeg mounts, custom spacers and covers.

Driveline spacers

Propshaft spacers, gearbox adapters, clutch components (non-friction).

Threaded specials

Period-correct fasteners — BSF, BSW, BA threads. See custom fasteners.

Out of scope: brake master/slave cylinders, ABS components, airbag systems, steering rack internals — anything requiring homologation or crash testing. We make structural and mechanical components.

Period-Correct Threads and Materials

Pre-metric British and American vehicles use thread forms that modern suppliers no longer stock: BSF, BSW, BA, UNF in odd sizes. We cut these threads routinely — a period-correct replacement rather than a metric compromise that ruins originality.

  • British classic threads: BSF, BSW, BA — gauged and cut to standard
  • American: UNC, UNF, including discontinued sizes
  • Materials matched to period: free-cutting steel, brass, bronze castings
  • Finishes: zinc plating, cadmium-replacement coatings, polished brass

How It Works

  • Send the original or photos — vehicle make/model/year and what the part does
  • Free CAD reconstruction — you approve the drawing before we machine
  • One piece or a small batch — no MOQ, spares at marginal cost
  • Worldwide shipping — tracked, with the CAD file included

Parts We Have Made

When "NLA" Is Stamped on Every Listing

What this page delivers is the end of the "no longer available" hunt — a part rebuilt from your worn or handed original, in metal or cast polyurethane, down to a single piece. Old cars don't stop needing parts just because the factory did, and by the time someone reaches us the marque forums have already drawn a blank. Here is who they are.

// Classic Car Restorer

"I'm mid-restoration and a bracket is missing — nothing like it has been made since the seventies"

Send the matching part from the other side, a worn original, or photos with one known dimension. We rebuild the geometry and machine it in steel or aluminium; where a part is handed we mirror it off the good side. One piece, no tooling fee — the way restoration work actually turns up.

// Specialist / Marque Garage

"I restore one marque and keep hitting the same unobtainable parts, car after car"

Then we make them once and keep them. Reproduce the hub carrier, the bracket, the trim mechanism from a sample; we hold the CAD, so the next car you book in is a reorder, not a fresh reverse-engineering job. Small batches drop the per-piece price for your shelf stock.

// Owner / Enthusiast

"I just need one window winder — it's NLA everywhere and the used ones are all cracked"

One is exactly our minimum. A cracked or worn original still makes a usable pattern — we recover the part as designed, not as it broke, in metal or cast polyurethane as the part demands. You deal with the shop that machines it, not a reseller sitting on the last worn one.

// Vehicle Builder / Resto-mod

"I'm building something bespoke and need adapters and spacers that simply don't exist off the shelf"

A dimensioned sketch starts it. Gearbox adapters, propshaft spacers, hub spacers, manifold flanges — cut from your measurements, CAD confirmed before a chip is cut. No minimum, period-correct threads (BSF, BSW, BA) where the build calls for them, and a couple of spares from the same setup for next time.

// Parts Vendor / Owners' Club

"My club members all need the same NLA part — it's worth remaking a small run, not just one"

That's the ideal job: we reverse-engineer the part once from a good original, then run a small batch so the per-piece price drops and your members aren't each paying one-off rates. The CAD stays on file for the inevitable next order, and you become the source for a part nobody else can supply.

Frequently Asked Questions

Yes — this is exactly what we do. Send the original part (worn or broken is fine) or clear photos with a reference dimension. We measure, rebuild the CAD for free, and machine a replacement. No OEM cooperation or part number needed.

Yes. MOQ is 1 piece with no setup or tooling fees on machined parts. Many of our automotive customers are restoring a single vehicle. We can also make a couple of spares from the same setup at much lower per-piece cost.

Safety-critical systems requiring homologation: brake master and slave cylinders, ABS components, airbag parts, steering rack internals. We make structural and mechanical components — brackets, bushings, fittings, hub components, trim hardware.

Yes. Small-batch polyurethane and rubber-like parts via vacuum casting — bushings, grommets, mounts, seals. Plastic trim components in cast PU or machined engineering plastic. For one-off rubber bushings, machined polyurethane is often the practical route.

Yes. Many car parts are handed — a left and right bracket, hinge or mount — and we machine the mirror image from the one sound side you send. Tell us it's handed and we mirror the CAD, so you don't have to find both originals just to end up with a matching pair.

Send photos of the part from a few angles with one known dimension — a caliper across a hole, or the bolt spacing — and tell us what it fits. We come back within 24 hours with a price for one piece, plus the lower per-piece cost if you want a spare. Worn, cracked or incomplete originals are fine; we reconstruct to design intent.

Restoration Stalled on One Part?
