QA1 Handling kit questions ???

I'm considering a QA1 handling kit install for my 68 340 Barracuda. My question is am I going to face any fitment issues??? I'm also looking at a set of TTI headers during the install. My car is a manual brake and manual steering with auto on the column. Just want to know if I'm going to run into problems BEFORE I spend a bunch of money. Or is there a better option???
I put the entire QA1 front with the K-member on my 68 barracuda notchback. Easy install. It handles well. Adding front disc. I have 15"x7" wheels. Old style headers are an issue and need to be installed with the suspension. I also have the rear suspension coming this week.
It is a lot of money, but really clean and easy to adjust. warmed up 318 auto. 5.9 on the horizon.
