Rear fenders?

If so, are you planning to bob them?

It looks very much like a Model A fender will work.

I held a steel bobbed 31 fender close to my highboy 32's fender well and it looks like the fender arc is the same.

I didn't hold the fender up against the 32 body because it's painted and I didn't want to scratch it.

I do know that 28-29 fenders will fit 30-31 roadsters and vice versa as long as they are bobbed.
The running board apron is different between the two Model A styles and the bolt pattern is different, but arc is the same.

30-31 fenders are 1" wider than 28-29's so there's a small advantage there if you're trying for a particular wheel/tire fit.

My guess is that A fenders are a lot easier to find in the UK than are 32fenders.
