Just put the fenders on my 36 Cabriolet restoration. I have two different front fender supports. One is 21 1/2" long and the others are 23" long, the short ones can be bent a little and will pull the fender in a little and the longer ones will push the fender out a little depending on where it attaches to the frame. Where are they supposed to attach to the frame???? Does anyone know the correct length for the brace?? Help! thanks Bruce
