Header Question

I have a set of Hooker Competition headers on a 71 Coronet 4-door. I need a set for my 69 Barracuda. Do the B and A body headers interchange? I have been looking at some on Jegs website and they show the same part number for both. I would like to save some cash and use the ones I have it they will work. My car is power steering if that matters. If any of you guys can help le tme know, I really don't want to waste time going out there pulling them of one car and spending a bunch of time trying to make them fit the Cuda just to find out they won't work.
