Mating Original Rear Fenders to Brookville Rear Quqrter Panels
 

Mating original ‘29 rear fenders to Brookville 1929 Roadster quarter panels.
I am having a problem getting proper spacing for the weltjng between an original undamaged rear fender and a Brookville quarter panel, I can’t get the space to be narrow enough. The problem is, the mating angles of the Brookville 1/4 panel and the fender are different . When bolted in place the mis-matched angle of the ¼ panel keeps the fender too far away to allow a tight fit of the welting.
Has anyone had the problem and come up with a solution?

yes, I have had the same problem and it was extremely frustrating. I found that buying the better-quality running board aprons, with the original-design offset flange on the one end, helped. as far as the rest of the fit, I ended up slotting out a lot of holes, both on the fender and the running board, to get a half-ass fit. I still could not tighten down the fender completely on one of the mounting bolts.

See pm too.

Short of slicing and dicing on the quarter panel to make it correct here is a low tech solution.

First, do the splash apron thing and slotting thing per Eric.
Second, get the fenders as straight and accurate as you can.

Now the big trick. Wax the fender with a mold release wax. Prime the wheelwell where the fender interfaces to prep for adding plastic body filler. Slather copious amounts of body filler to the area of gaposis. Bolt the fender to the body before the body filler hardens, the excess filler will extrude out. Allow the filler to fully harden. Remove the fender (it should release easily if is waxed properly). Grind and sand excess body filler from the body. Perfect fit... just like the body was made for the fender.

Seems it would need to be slow setting filler to have time to bolt a fender on . Good luck with that .

The filler will set slower if you add less hardener, or work in a cooler garage or in the evening.
