At the NSRA York, PA SR Nationals there were 2 Brookville 30-31 roadsters and neither had fender or running board welt. Both fit up well and looked great. My intent is to cut the actual rounded welt off of mine and just use the web portion for anti squeek as my fenders and RB's fit just fine - and about the only parts on my POS body that do - probably because the front fenders are Wescott's and the rears are Albrecht's with the RB's and splash shields being Lobecks.

Just a note - Brookville had a primed '32 and a primed '30-'31 body at York. The '32 was fair and the '30-'31 had most of the same hills and valleys that mine has, with the trunk lid again being the worst piece. My guess is that if you were to buy one of their bodies unprimed, you will get better workmanship as they can't hide their visually obvious mistakes under a load of their cheap primer.
