Demon front end conversion. INPUT??

If you can find the dart parts.I did the same swap on a 73 duster a few years ago,and later swapped the tail panel for a demon piece i lucked up on.Now i have a 71 swinger i bought without a front clip,and cant find one close to me,not a complete on anyways,lol
ill have to wait til Mopar nationals in Carlisle Pa to get the stuff i need then. itll be an on goin process. ill wait till i get alll the parts before i start puttin it together. but do i need the Demon fenders?
