More good ideas. Thank you.

2-i: That would be the perfect solution, and that was my first thought. I just don't have extra or pieces of p65's.

coldfeet: I have the 60-mm Big Apples. I haven't measured how far out the fenders are from the tire, but it looks like about 3 to 4 millimeters on each side. That's not optimal coverage perhaps, but it seems to be sufficient. And like I said above, I road in the rain the other day and I got no spray from the front tire on my shoes, BB, chain, etc. I had to file some material on both sides of the fender at fork to get a good fit. I installed them without filing at first, but there was pretty much deformation. The bike is mid-80's MB-2. I don't think there are wider fenders on the market.
