I've an old set of old Doug Thorley headers on my bird, want to get a new set of long tube ceramic coated headers. I found the Doug's Headers D569 ceramic coated ones. Can someone who has these on his/her car tell me how they fit and if they hang down, what clearance is like? Mine is a Pontiac block, power steering, non boost manual brakes, standard transmission floor shift.

I had to remove some of the clutch linkage to get the thorleys off and on as well as bash, I mean massage the pipe to clearance the steering box. Don't want to bash a new set.
Thanks
