# NOS Door Seals for 1970 MGB Roadster

Vehicle & Part Overview

Finding NOS (New Old Stock) door seals for a 1970 MGB roadster presents a genuine sourcing challenge. These small rubber components perish over time, and most surviving examples from the 1970s have already been used or replaced. However, with patience and persistence, sourcing is achievable.

Sourcing Recommendations

Primary Suppliers

Start your search with these established British Leyland specialists:

  • Moss Motors — Carries MGB-specific weatherstripping and seals. Your first proper stop for British Leyland rubber components. May stock both NOS and quality reproduction options.
  • Rimmer Bros — Also stocks MGB trim and seals. Inventory rotates regularly, so one supplier may have stock when the other doesn't. Worth checking both.

Secondary Sources for NOS Stock

  • eBay Motors — Search for "MGB door seal NOS" and "MGB weatherstrip NOS". When evaluating listings, check seller feedback specifically on similar rubber components. Always ask sellers about storage conditions before purchasing — rubber from the 1970s stored properly may remain supple, but much old stock has hardened over decades.
  • Hemmings — Runs classifieds where restorers sometimes list NOS stashes they've discovered.

Safety & Fitment Notes

Water Ingress Risk: Poor door seals on a roadster create significant water ingress problems, leading to rust damage that costs substantially more to repair later. Do not compromise on seal quality.

If NOS sourcing proves impossible, pivot to quality reproduction seals rather than pattern alternatives. Both Moss Motors and Rimmer Bros carry reproduction MGB seals that provide reliable performance and proper weatherproofing for roadster use.
