I thought I found it..

After searching the web, I found a nice little round fuel tank from the Flakekings guys .http://flakekings.blogspot.com It looks great,but after putting  it on the frame, it was too small...Shit! The search continues.... But the good news is that I ordered a 19 inch and 16 inch rim.Cant wait to paint them black and fit them in the bike!! Also bought an old yellow headlight that fits great with my expectations.
