Patricia I'm copying my answer I gave you on the other side since they'll probably delete it now that you've started the same thread over here.
Patricia you need to look for a cabinet that was made for the 401/500 and up machines. One of those will most likely have the front clips built in, the way to tell that type of cabinet is it won't have the "flap" on the right side of the front folding piece of the cabinet. Some of the older cabinets that have the "flap" will have the front clips in them, most don't. The cradle mounts into the cabinet on the hinge pins, then you set the machine into the cradle. Most people who remove the cradle to sell it don't think to remove the clips with it.
Your machine is very pretty, I love the black 301s. I might be taking mine to the PNW get together we're having on March 13th.
