It still is hard to tell it's so close I can't be positive. It sound pretty tight under the fork crown. I'm on good terms with the place I bought the fenders, and they let me try them with the condition that if I did not scratch them all up I could return them. Also It is possible to end the back section of the front fender at the back of the fork crown and then continue the other piece in front. Are you OK with making brackets and cutting the fender. Or experimenting? In other word neither fender has to go under the fork or the brake bridge if you are willing to cut them and make a bracket to hold them in place. It may not look too good. I've done it on bikes that I don't mind if they look a little messy. If you are doing mail order from Performance you can probably get your money back if you don't damage them. They have a good return policy.
The front fender that is very close on one of my bikes sometimes gets a small stone and rolls it right up the fender and out the front. A little more clearance would be better, but I have put a few thousand miles on it the way it is with no problems.
Nice looking bike, somebody took very good care of it.
