The left(driver's side) exhaust manifold is cracked. This truck was ordered new with "Ranger" package and all options, so it has the factory
installed A/C. There's a bracket from the A/C compressor that goes down and bolts to the top of the exhaust manifold. The replacement I got had correct casting number, but doesn't have the hole drilled and tapped for the A/C
bracket in the square "boss" on upper side of manifold. Does any one know the correct angle of the exh. manifold mounting surface on the head, in reference to verical? I would need to know this to set up a jig to hold head at proper angle, then drill and tap a hole in the vertical plane. Also, I know I'll probably have difficulty with at least one bolt when removing them for replacing the manifold. Any gotcha's or advise to make
this process as painless as possible? I REALLY don't want ot have to pull head because a bolt wrung off! Thanks, in advance, JR in N.C.
