Really helpful link to youtube guide to fitting headers on page seven here. I have a slight problem. I am unsure as to where (on twin cam GS ) the 02 sensor connectors are located. I think they maybe underneath the cylinders. There in is the problem as this area is covered by a plastic shield the third and vital screw to which i cannot remove without removing the engine bars 
So before i go taking the bars off can someone please confirm this is indeed where i should be looking.
Thanks Dario.
