'65 Dart 4-speed

[3403spd]

Hi all! Ive got a '65 Dart 2dr that is in excellent original condition, 225-3spd, with 50,000 original miles. What I want to do is put a 340 4-spd in it that I have. I have everything I need to do the swap except headers. I was considering the Dougs or TTI under chassis headers but am leary after reading the post about 10 1/2" clutch clearance problems. I also considered the Headman fenderwell headers but have also heard of steering radius problems with those. Also does the factory mini starter fit with both the Dougs and the TTI's or not? And is the TTI trans crossmember needed to put exhaust on or are they just trying to sell parts? Any help is awesome!
