Your welcome..........I bought an old Manitou fork off the bay last winter that had supposedly been rebuilt with extra heavy springs installed and when I received it, it had zero rebound with some of the original elastomers missing. Misrepresented for sure, but that was one of the online retailers I came across in an effort to correct the problem. Finding some Girvin springs may take some extensive searching. If thats the same ProFlex that was on Chicago CL, I took a long look at it myself, but decided not to persue it.............Happy Trails
