You can change it out later. Theyre seperate pieces, atleast on the 94 gt i had. I put a new top on st the same time as the headliner, but the top goes over the frame and the headliner goes under to hide it. Not a week later i got home from work and my brand new top was shredded, the f'ed up thing is i live like a 1/4 mile off the road and my car wasnt visible from the street. Somebody didnt like my new top, the damn car wasnt even running
