If you’re restoring a pre-1980 vehicle, small details separate an average build from a truly correct one. One of the most overlooked finishing touches is the windscreen wipers. Modern blades can look out of place, while classic style wipers keep the correct era look and still deliver reliable wiping.
In this guide we’ll cover:
- Why old school wipers suit pre-1980 vehicles
- The common buying mistakes (and how to avoid them)
- How to choose wiper arms and wiper blades that fit and look right
1) THE LOOK: PERIOD-CORRECT FINISHES THAT MATCH THE ERA
Classic cars were designed around brightwork. That’s why many restorers prefer hand polished stainless steel arms and blades—especially when they’re English made and designed to replicate original-style proportions. The result is simple: the wipers look like they belong.
2) THE FUNCTION: FITMENT IS EVERYTHING
Even the best wiper blade won’t perform if the connector or geometry is wrong. The biggest causes of poor wiping are:
- Incorrect blade length
- Incorrect arm mounting style
- Incorrect bayonet/arm width (common on classic applications)
- Weak or inconsistent arm tension
A key performance detail: spring loaded blades help maintain positive contact with the windscreen, which reduces missed patches and improves wiping consistency—especially on older curved glass.

3) QUICK BUYING CHECKLIST (THE 3 CHECKS)
Check #1 — Blade length
Measure the blade length currently fitted (measure both sides – some vehicles have different length blades!). Too long can hit trim; too short reduces visibility.
Check #2 — Connector and arm width (5.2mm vs 7.2mm)
Many classic and old school wipers use bayonet fittings( as well as “Spoon” type) and commonly come in two key arm width options:
- 5.2mm arm width (bayonet)
- 7.2mm arm width (bayonet)
If the width is wrong, the blade can feel loose, sit incorrectly, or perform poorly.
Check #3 — Arm condition and tension
Old arms often look fine but have tired springs. If you get streaking or skipping, the arms may be the real issue, not the rubber.
4) WHAT TO BUY (AND WHY)
Option A: Full wiper kit (best for restorations)
A matched kit (arms + blades) reduces fitment errors and gives a consistent finish.
Option B: Blades (best when your arms are proven and strong)
If your arms are correct and tension is good, blades are often the quickest fix.
Option C: Arms (best appearance upgrade)
If your arms are pitted, mismatched, or don’t park neatly, replacing arms often improves both presentation and wipe consistency.
FITMENT CORNER (SAVE THIS)
- Take a clear photo of the arm base and the wiper post/spindle.
- Confirm whether you need 5.2mm or 7.2mm arm width. If unsure, measure the width of your existing arm.
- If your goal is better wiping (not just better looks), prioritise spring loaded blades for positive contact with the windscreen.
FAQ
Q: Why do classic style wipers look better on pre-1980 cars?
A: They match period styling and brightwork, so the car looks correct rather than modernised.
Q: What’s the most common reason classic wipers fit poorly?
A: Ordering the wrong arm width—5.2mm vs 7.2mm—so the blade doesn’t seat securely.
Q: How do I know if I need 5.2mm or 7.2mm arm width?
A: Measure the width of your arm or check how your current blade seats and locks in.
Q: Do spring loaded blades make a real difference?
A: Yes—spring loaded blades help maintain positive contact with the windscreen, improving wipe consistency.
Q: Are English made parts worth it?
A: If you want a period-correct finish and consistent manufacturing, English made and hand polished stainless steel options are popular with restorers.
