Thanks all for the input. I found some SKS fenders at the local sporting goods store (50mm), and installed them on the bike this weekend. It took me around an hour, and the only modification I had to make was a hole drilled through the rear fender to accept a mounting bolt into a threaded hole between the seat stays. Otherwise, it was like the fenders were made for this bike.
The bike just looked naked without fenders. Now with a Wald handlebar basket, the bike is functioning and looking just about right.
Thanks!
