Mercedes R129 Door Mirror Triangle Trims A1297200711 A1297200811

This is a precision-engineered replacement for the interior door mirror triangle trims on the Mercedes-Benz R129 SL-Class. The factory trims — OEM parts A1297200711 and A1297200811 — are highly visible interior pieces that crack, discolour, and delaminate from age and UV exposure. We re-engineered these trims in ASA to restore the R129's interior to a factory-correct finish with parts that will not fail again.

✅ COMPLETE PAIR — LEFT & RIGHT: This listing includes both the driver's side (A1297200711) and passenger's side (A1297200811) trims as a matched set, in your choice of interior colour — Black, Grey, Cream Beige, or Mushroom.

The Engineering Edge

• ASA Construction: Moulded from engineering-grade ASA, these trims are UV-stable and heat-resistant — engineered to maintain their finish and dimensional integrity in the intense cabin heat of an open-top SL, where factory plastics consistently degrade.
• Exact OEM Profile: Every surface contour, clip position, and edge detail is reverse-engineered from the original parts. The trims install and sit identically to the factory pieces with no gapping, no proud edges, and no visible fitment issues.
• Discontinued Part Solution: Original supply of these trims is exhausted from Mercedes-Benz. Used examples are already in the same degraded state as the parts you're replacing. These are new-manufacture reproductions, colour-matched to the factory interior tones — available in Black, Grey, Cream Beige, and Mushroom.
