Best fittting headers for 69 340 GTS ?

As you may know,, both headers require the mini starter,, you mention automatic,, if it's a console shift, I've found it nec to do this mod to the lower shift support..

Applications with an Auto Transmission & Floor Shifter will require the adjustable swivel and the lower rod attached to the torque shaft lever to be re-positioned to clear the header collector [ame="http://ttiexhaust.com/PDF/FN23-SHT3703-TorqueShaftLever.pdf"].[/ame]

If you'd had a clutch,, there is a moded z-bar that's covered here..

there was a great thread not long ago about moding it yourself by moving the bell side lever over..

hope it helps..
