96-98 to 99-04 long tube headers

[8.8mustang]

I have a set of bbk long tubes and x-pipe for my 97 cobra that I am now going to I think just part or sell that car. Hear is the question, are the headers the same as the 99-04 anyone know the difference. The part #'s don't seem to be the same in the summit I am looking at. But will they work for my dad's 99 cobra? I want to know before I pull his car a part and go threw the trouble of finding out they are not going to work. is it just that I have to lengthen some wires?

I think the exhaust ports are different between the 96-98 4V, & the 99-04 4V? So in other words, I don't think they will work. But I'm not 100% sure, so I could be wrong?
