I looked at the fenders an hour ago. There isn't a pair of '31's. There is a right front '31 and a right front mid '28 to '29. The '31 "looks" good for most of it but the bead is bad most of the length with welded strap steel inside. It is $245. The other fender is actually better though it has a large rust hole near the running board end. It is $85. The mall can take 10% off or will call the owner on offers. Obviously, this is my opinion.
Sorry for the mis-information Roger, Just looked at them in passing, really didn't have an interest and didn't think of posting it here until I got home, you would have thought I could tell they were both passenger side though.
