NEXT COMES THE SPINNER

Since the fuselage is looking reasonable it was time to add a spinner. 

I have one nagging problem.  Just at the shoulder level to the pilot a polygon of the fuselage is all alone joined to the rest of the fuselage on only two edges.  That causes C4D to throw a "hissy fit" and generate an n-gon.  Now, everything renders and looks fine.  But the UV map of the surface is all "goobered up" because the adjoining polygon has five points.  I have not discovered how to solve that problem and it "nags" on me.  I have tried all manner of things but any action makes things worse and not better.  Suggestions?
