Vagabond Posted August 23, 2011 Report Share Posted August 23, 2011 Looking for the dimensions for the 4 bolt flange on a NA 850 exhaust manifold. Unfortunately I can't afford the downtime to take mine apart for measurements and my exhaust is in such rough shape if i did it probably wouldn't go back together. Much appreciated.

erikv11 Posted August 25, 2011 Report Share Posted August 25, 2011 I have one in the garage, what dimensions do you want? Just the linear distances between the bolt holes? Link to comment Share on other sites More sharing options...
erikv11 Posted August 25, 2011 Report Share Posted August 25, 2011 It is basically a trapezoid but the legs seem not exactly the same length. Measuring center-to-center between the studs that are still installed in the one I have: top = 2-1/4 inches bottom = 2-5/8 side1 = 3-1/8 side2 = 3-3/32 Link to comment Share on other sites More sharing options...
erikv11 Posted August 25, 2011 Report Share Posted August 25, 2011 Here is a pic taken from as near parallel as I could. The diameter right inside the edge of the exhaust hole is 2.670 inches according to my high end Harbor Freight digital caliper. What I called "top" (2-1/4 inches) is the left edge in this orientation. Print it out at the right size and you have a template.pic Link to comment Share on other sites More sharing options...
