Reproduction Parts

Modern-manufactured replacement parts designed to replicate original Ford parts for classic Mustangs. Made by aftermarket companies, not Ford, using reverse-engineering from original parts. Also: the reason you can actually complete a restoration in 2025 instead of waiting decades to find NOS parts, even though concours judges will deduct points for your very-nice-but-not-original door handles.

What 'Reproduction Parts' Actually Means

Reproduction parts are newly-manufactured components designed to fit and function like original Ford parts, but made by aftermarket suppliers 50+ years after the originals.

How reproductions are made:

Process:

  1. Acquire original Ford part (NOS or good used)
  1. Reverse-engineer dimensions, materials, finishes
  1. Create tooling (molds, dies, stamps)
  1. Manufacture using modern processes
  1. Package and distribute

Quality levels:

Budget reproductions:

  • Cheapest option
  • Made overseas (usually China)
  • Adequate fit (requires adjustment)
  • Materials acceptable but not original-spec
  • Cost: 30-50% of premium reproductions

Standard reproductions:

  • Good quality
  • Better fit than budget
  • Decent materials
  • Most common choice
  • Cost: Standard pricing

Premium reproductions:

  • Excellent fit and finish
  • Original-spec materials when possible
  • Better QC than standard
  • Brands: Dynacorn, Scott Drake, NPD premium lines
  • Cost: 30-60% more than standard

Concours-correct reproductions:

  • Exact replicas of originals
  • Correct finishes, markings, details
  • Best available for concours builds
  • Brands: Distinctive Industries (interior), specific suppliers
  • Cost: 2-3x standard reproductions (but still less than NOS)

I've used all quality levels. Budget door weatherstripping ($40) leaked and fell off in 6 months. Premium weatherstripping ($120) fit perfectly and sealed great. Sometimes you get what you pay for. Sometimes budget is fine. Know which parts matter.

Why It Matters for Your Mustang

Reproductions make restoration accessible and affordable for 95% of Mustang owners.

Reproduction advantages:

  • Available (order today, receive in days)
  • Affordable (1/3 to 1/10 NOS cost)
  • New condition (no 50-year storage issues)
  • Warranty (typically 1 year)
  • Modern materials (sometimes better than original)

Reproduction disadvantages:

  • Not original (concours deduction)
  • Fit sometimes imperfect (varies by part and manufacturer)
  • Quality varies (budget vs premium)
  • Date codes wrong/absent
  • May lack original markings

When reproductions are perfect:

  • Show quality builds (appearance matters, not originality)
  • Driver quality builds (function over authenticity)
  • Budget restorations ($40,000-$70,000 range)
  • Common parts (extensive selection)

When NOS is better:

  • Concours builds (originality required)
  • Ultra-rare cars (Shelby, Boss)
  • Parts with fit issues (reproductions don't fit right)
  • Investment-grade builds

The 90/10 rule:

90% of restoration parts should be reproductions. 10% might benefit from NOS (if you can find and afford it).

Cost Impact

Repair TypeTypical Cost (LA)Labor Hours
Interior kit (premium repro)$3,500-$5,000NOS $8,000-$20,000, saves $4,500-$15,000
Weatherstrip (full, premium)$600-$1,200NOS $1,200-$3,000, saves $600-$1,800
Chrome bumpers (premium)$1,200-$2,000NOS $2,000-$5,000, saves $800-$3,000
Complete restoration (premium repro)$25,000-$45,000NOS build $60,000-$120,000, saves $35,000-$75,000

*Reproduction parts make restoration affordable - 1/3 to 1/10 NOS cost. Premium reproductions offer excellent quality for show quality builds.

Ask me how I know these numbers.

Common Issues

Fit Issues

Dimensions slightly off, mounting holes don't align, gaps at edges - requires trimming or adjustment

Quality Varies

Budget vs premium - some excellent, others terrible - research specific parts before buying

Not Original

Concours judges deduct points - not acceptable for concours builds

Date Codes Wrong

Reproductions have modern dates or no dates - immediate concours disqualification

Material Differences

Thin metal, cheap plastic, wrong rubber compounds - varies by manufacturer and price point
