I put motorcycle style front fenders on my '29 Speedster by drilling the backing plates a fabricating brackets to go up to the fenders. The fenders turn as the front wheels steer. I can't send you pictures as I am at our winter residence in Texas and won't be home until mid March.
Where did you find the fenders? I could not find any the right size so I made them out of wood (a lot of work!). I would like to replace them with metal fenders. I haven't put rear fenders on yet.
