TTI 340 headers install

I have a 68 Barracuda, with a K-member from a 70 Duster, steering from a 73 Dart, and a late PowerSteering box from an unknown source, with standard 73up steering arms.
The engine is a 71-360 with a Milodon roadrace pan, the trans is a Commando A833, the guts from a 65, and with all standard 1969 340 type clutch linkage.
I used the 73 up rear trans mount for the spool locator.
The engine was shimmed up about 1/4 " per side, plus another 1/4 on the driver's side to get away from the P/S box. The TTI headers were a tight fit, but everything slipped together real nice......
Except:
on the driver's side;
I found out after the engine was in, that the 72 and down steering would not fit without some bullchit pounding. But the 73 up stuff was good to go, with minor interference at the pitman arm.
No problems whatsoever to the column, which was the original manual steering, auto trans/console-shift item, length-adjusted to fit the P/S box by shearing the nylon rivets.
Minor clearancing at the Power-steering box.
On the passenger side,
install a shorty oil filter on the pad without the 90* adapter; you'll thank me for that tip one day.
and then ......
At the top
a Holley 750DP on an AirGap intake, pushed the factory air-cleaner lid right into the hood. No problem, the jig-saw took care of that in just a few minutes and the bonus is I now have a true fresh-air intake.......
Oh, I almost forgot
at the back
this job is a stinking lot easier if you take the T-bars out before you start. You're gonna have to anyway, to clearance at least one pipe, so it don't rattle on the bar, lol.
Tips
use the thickest darn manifold gaskets you can find, which may spread the headers enough to clear 318 T-bars . Install them/torque 'em/ forget about them for ten years or more.
Do TTIs fit perfect? Not on my car! But what header would?
