I haven't worked on the fender flares yet, sorry. I have an extended break from work over Christmas so hopefully I can get some work done on the car. I have seen some others who have used the fender flair from a 71-73 mustang and it looks pretty good. http://www.lateral-g.net/forums/showthread.php4?t=44342
Another option would be too use the fender flare from a Volkswagen rabbit. Good luck.
