Rear fender alteration
 

The wooden body on my huckster is 5" wider than the mounting flanges for the 1930 coupe fenders. For the fenders to attach correctly to the running boards, I need to remove 2 1/2" from the inside edge of each. I clamped the fender to a flat surface (old door), scribed a line 2 1/2" up, and cut it off. Learned by several methods of trial and lots of error that inserting the removed flange to the remaining fender body is quite difficult. Photos show where I stand right now. The flange is spot welded (lots of spots!!) to the inside of the fender, but I haven't started any welding on the outside. I am past the point of no return for this fender, but I would like any recommendations from the audience on how to finish this, and avoid the same difficulties with the next one

I have to do the same modification to the rear fenders for my huckster too. I think the best solution is to remove the 2 1/2 inches from the middle of the fender rather than the edge. That way you lessen the problem of having two halves with different radius to weld back together.

Here is a shot of my left fender completed. For the right side I will modify a 28-29 sedan fender. It is too narrow, so adding to it will be easier (for me) than cutting away. In comparing my finished fender to its untouched companion, I lost about 3" of span from running board to tail. I think your recommendation to take 2 1/2" out of the middle is the best idea. You will still need to plan how to mate the fender to the splash apron
