OEM Turbo Wastegate Flapper Assembly – Excellent Condition – Buick Grand National / Turbo Regal / GNX

🔥 RARE OEM WASTEGATE FLAPPER HOUSING – NEARLY IMPOSSIBLE TO FIND THIS CLEAN
This is a genuine GM internal wastegate puck housing pulled from a factory Turbo Buick. It features the original spring-loaded puck and cover plate that controls exhaust bypass on stock-style turbos. Structurally excellent, with only minor surface rust. These are no longer reproduced and getting harder to find — especially in this condition.

✅ OEM spring-loaded puck + housing
✅ Excellent condition – just surface rust
✅ Used Sealing ring included
✅ No cracks, damage, or thread issues
✅ Must-have for factory-correct restorations

🔍 Fits: 1986–1987 Buick Grand National, Regal T-Type, Turbo T, and GNX (OEM turbo setups)
