OK, if you look at the picture of the chassis in my photo album, you will see that the gum rubber bumpers you have go into the block of wood and push the chassis up forward into the cabinet more. This should give you enough of the shafts poking out to install the knobs. The 1/4" carriage bolt holds most of the weight, but there are two small holes in the block for wood screws. They will keep the block from turning once it's in the final position.
