Damn, if I knew you hadn't thrown that headache away already, Id buy that driver side flange.....1/4 inch flange is pretty flimsey especially since the LA has the wide bolt spacing on the 3-5 ports. And don't get me started on that stupid Hooker 'O-ring sealing' garbage when they dont even fit the shape of the head ports.....run a good MLS gasket...paper ones will burn.
