The Lisle Corporation Manifold Drill Template, No. 68500, is designed to remove broken exhaust manifold studs on 4.6L, 5.4L and 6.8L V10 two-valve and three-valve Ford Triton engines without damaging the cylinder head. Interchangeable plates and alignment pins help center drill on the broken stud. A depth gauge for drilling is marked on the template and the stud extractor is then used to remove the broken stud.
