Direct-Bond Quarter Lights on Newport Pagnell Coachwork
Replacing the stationary rear quarter light on these hand-built supercharged coupes means working against hand-beaten aluminum bodywork where every single aperture varies by millimeters. Unlike the drop-top Volante variants that utilized motorized drop-down quarter windows, the coupe models—ranging from the base twin-Eaton supercharged V550 up to the Works V600 package and the final Le Mans editions—rely on fixed glass permanently bonded into the structural side aperture. Because Newport Pagnell craftsmen shaped these body shells individually, no two window openings are precisely identical.
The glass sits flanked by delicate exterior finisher assemblies: the vertical cheater finisher panels along the door shut pillar interface (factory part numbers 77-63014 for the right side and 77-63015 for the left side) and flush-fit perimeter mouldings. On the cabin side, the aperture is lined by hand-stitched Connolly leather quarter casing panels and bespoke headliner trim retainers. The physical glass lacks heating filaments, embedded radio aerials, and acoustic film layers, but it does carry a dedicated ceramic frit band designed to shield the bonding track from solar exposure alongside a subtle green tint engineered to balance the front side door glass.
Variant Details and Factory Reference Numbers
Because these vehicles were fabricated in double-digit annual numbers rather than stamped on automated assembly lines, standard NAGS reference codes do not exist for the quarter lights. Sourcing relies on original Newport Pagnell part references or classic aftermarket runs.

|---|---|---|---|
| Left-Hand Quarter Glass (Nearside UK) | 76-65375 | V550, V600 Works, Le Mans V8 | Fixed, green tint, ceramic border |
| Right-Hand Quarter Glass (Offside UK) | 76-65374 | V550, V600 Works, Le Mans V8 | Fixed, green tint, ceramic border |
| LH Pillar Cheater Finisher | 77-63015 | All Vantage Coupes 1993–2000 | Exterior B-pillar interface strip |
| RH Pillar Cheater Finisher | 77-63014 | All Vantage Coupes 1993–2000 | Exterior B-pillar interface strip |
When original dealer stock is exhausted, I rely strictly on specialized aftermarket glass from manufacturers like Pilkington, PGW, FYG, or XYG to secure panels that mirror the factory edge profiles and curvature. Matching the radius on these cars is critical because excessive gap variations between the glass edge and the hand-formed aluminum waistline will lead to wind buffeting right behind the driver's ear.
Managing Aperture Tolerances and Weatherseals
The transition zone between the door glass frame, the B-pillar shut seal, and the leading edge of the quarter glass requires intense scrutiny. On the 1999–2000 V8 Vantage Le Mans—built to commemorate the 1959 victory—the body margins remained exceptionally tight despite subtle exterior styling revisions elsewhere on the car. If the replacement quarter glass does not match the exact perimeter contour of the original pane, the door's secondary weatherstripping cannot seal cleanly against the B-pillar upright, which drops water behind the Connolly trim and directly into the rear seat pans.
- Perimeter frit alignment: The black ceramic band must sit completely inboard of the aluminum aperture edge to conceal the bonding line while remaining invisible past the interior pillar trim.
- Finisher clearance: Retaining clips on the 77-63014 and 77-63015 B-pillar finishers demand consistent lateral spacing; an offset of just one millimeter can prevent the finisher from snapping flush against the trailing door frame.
- Panel depth: Hand-filed aluminum waist reveals require measuring glass thickness before setting the depth, ensuring the outer surface planes out evenly with the adjacent rear wing sheet metal.
