Header question

I have a 72 dart swinger with a 4 speed and I have Dougs ceramic coated headers $700 bucks...

The Z Bar is a fit issue and I have the TTi Z Bar and I've tried 2 others stock and a modified and still rubbed before I had to get the torch out.

Just installed a smaller than stock Borgeson steering box and it was a nightmare with the clearance.
I paid big money for these with props and thumbs up before I got them... they look awesome but have fitment issues
