My '95 Dynasty 300 Cummins has developed 4 broken bolts on the two front cylinders
,,, #1 and #2 (?). I plan to pull the manifold with turbo attached and remove turbo on bench. I need to drive moho about 50 miles for the 4th. I don't want to disable it until after the 4th. I plan to "c" clamp the manifold just to reduce vibration and breakage for the short trip. I plan to upgrade the bolts and the old bolts appear to be a grade 5. Could they be that soft or are metric marked differently? Can I upgrade the manifold to a 2 piece? Please, no comments on the clamps! THX
