My Hooker headers fit fine on my A-body 70 Duster 360 with no clearance problems. Raise the torsion bars alittle and welded a skid plate for insurance on the driver side tubes.
For like $169 they seem to be still a good product for the money.
Ask the 4spd guys about their fitment issues with TTI's.

Moparless for now but when the opportunity is right I'll have another one.
