you can cut off the lip, then install the front supports. I swapped front flaps on two cabinets so I could put a 403 in a cabinet that had a 15 in it to start with. However I swapped them back when DH decided he didn't want to use the 403.
Forgot that you do have a cabinet for the 301 - can you take that flap and install it in the nicer cabinet? It may be a better option to refinish the flap and trade them than modifying the original. Though if you never plan on going back, then you'll not have a problem.
I've got around 20 different singer cabinets, and a few with the cradle setup and a few that were for the newer machines.
