Covering GM LS III 4.8L, 5.3L, and 6.0L motors, this manifold drill template removes broken exhaust manifold bolts without damaging the cylinder head. Tapered bolts center the base plate over the bolt holes, while a slip-fit bushing allows for movement between holes without repositioning the base plate. To prevent piercing the water jacket during the extraction or tapping process, the tool includes a double-sided drill depth gauge.
