Is there any fitment problems with TTI- Big Block -A body

ive had the 1 3/4 tti since they came out. i had the same issue with pitman arm stud as 5.7hemi. on my 69 dart. when i put the 2" on it, the 1 3/4 went on my 74 duster. i didnt have the pitman arm issue with the newer steering. the tti do clear stock ps box butbit is TIGHT. last year i went with the borgeon box and theres all kinds of room. i think that box might clear 2" headers.
