I got this message from Jon in AZ but don't see it in the thread. So I am posting his suggestion here hoping it may help others:
"I assume you mean the two small side-saddle upper cabinets?
Another option might be replacing the MDF cabinets with the newer molded
fiberglass versions from Scamp. I think the change came after the 2006 factory fire, and I can't say for sure if they will fit your pre-fire unit, but Scamp could tell you.
The
fiberglass ones are installed with rivets at the factory, but you could also install them with SS bolts, washers and lock nuts.
Not the cheapest solution, but IMO they look better, and with bolts they'd be quite strong."
Thanks for the suggestion, Jon! If my fix does not work out I will look into purchasing the
fiberglass cabinets from Scamp. It would be expensive because of shipping but it is definitely an option.
