The guy who can probably answer that is either 68CBarge or HemiFury.  Possibly Snotty too.
 
Let me look on the main site and see if I have a picture of that.  Seems to me I do.
 
Those guys are regulars, so check back in a day or so.
 
In the mean time
 
WELCOME!

I just went through a few possibilities.
 
It seems to me it goes on the outside of the torsion bar, and yes it is close to the steering box.
 
I would, if I were you, install an oil cooler in the power steering return line.
 
I haven't done one of those in years, but I will be on my Fury Vert soon.

Thanks for the kudos Steve, but my car was originally a 383 2 bbl with a single exhaust.  My current system is custom.
 
Welcome '69!  I assume you have the 350 HP 440 since you are adding the HP manifolds.   I would recommend against using those as they make it a real pain to change your spark plugs.  However, they are cheaper than trying to go with a custom header.

The pipes go inside the torsion bars-the one on the drivers side should have a fairly tight turn right at the top where it bolts to the manifold. (see pics)

Yeah,what Kraut said.
I have the TTI system on my 68 New Yorker and it fits like a glove.Quiet on the highway at cruising speeds and barks when thrust upon.
TTi says you may need to use an adaptor for the trans linkage--but I did not need to do that.
Make sure you disconnect the battery before installing the front pipe!! (I got zapped when the pipe touched the starter,LOL!!)

I have to disagree here,   the C-bodies go outside the T-bars.    My 70 SF still has it's original headpipes ( at least the first 3 feet! ) & they go outside.

If you look at the first 3 pics that looks like a B-body,  the notches in the trans X-member are inboard as all A-B-E's are.    The bottom pic with the headers is a C-body,  look at  the hard turn  the headpipes make to go out to the notches in the X-member.  All the C-bodies have the notches in the X-member outside of the T-bars.   All of them we've had done here are outside & that's either with the lo-po or High-po manifolds.

Here's a shot of the original single exhaust on Chaz...note the left side goes inside the t-bar and the right side goes outside the t-bar.  I'm pretty sure that would remain the same for the fusey C's since the basic under-pining platform wasn't changed that much, but it is a guess on my part, too, so I COULD be wrong.

The first two pics are my '68 Newport with HP manifolds and TTI pipes, the third is a B body, the last is a '68 300, and the pics don't lie.  All the pipes go Inside the torsion bars where they meet the manifolds - they do eventually go below, then outside the torsion bar so they can pass through the cutouts in the cross member.  I guess it all depends on who makes the pipes because it looks like you could bend them to go on either side of the bar.
