Thanks guys!
I did some more work on it and ordered the chrome "V" and star nuts. (still not sure if I will put the star nuts on it as I think it looks pretty clean as-is).
Just looking at pics of the original it seemed to peak in the middle but then the entire thing canted back behind the "V". This is just .190 aluminum so I'm not going to try to put a bunch of curves into it but I still made the top out of 2 pieces to somewhat emulate the original.
I'm thinking at this point I will do the engine in the original colors. (Gold batwing and valve covers, everything else dark blue).
