We have a 23 y.o. Amana side-by-side, model sx25sw p1190214ww. We've neglected it and lost some a crisper/hydrator bin and associated shelf over the years, but I've just fixed some running issues that turned out to be nothing more than deteriorated connections in the evaporator compartment. Finding all the other critical running mechanicals and electricals in amazingly good shape, I've gotten religion to take better care and restore missing parts.
So I've noticed that the refrigerator compartment is just over 18" wide. Shelving is supported by tracks with about 17" spacing, center-to-center. My question is whether these are standard dimensions, so that shelving and bins from other brands and models could be swapped in? There are lots of side-by-sides of similar vintage being offered free on Craigslist. What are the chances of these parts from a similar-sized GE, Whirlpool, etc. etc. fitting?
