I was at auto parts store today, so i as for 89 240sx sohc manifold gasket to compare to f2. the 2 center hole lined up, also the 2 bottom hole lined up. intrigue by this, i snapped pic.
f2 gasket overlay 240sx ka24e gasket
remember i widen the holes on the f2 gasket to fit over m10x1.25 stud instead of m8, thats why the hole is larger compare to the nissan gasket
