65 Dart Exaust Manifold Removal

I have a 66 with PS that is not the problem. It has more to do with kick-down linkage on automatic. The outlet end just passes in the firewall indentation located between steering column and rear of head. The bell crank for kick-down likely needs to be removed from head to make room. Valve cover off too may help.

The end stud might also be a problem, since the manifold has limited distance to inner fender. Loosen motor mounts to shift engine slightly if more room is needed.

About manifold cracks:
The end bolts on manifold should have special washers, and tightened to specification. The manifold expands when heated, so the ends move out. Too tight on the bolts, may crack the manifold ears at bolt holes.
