This reminds me of some of my silly things you end up doing. Some ask me where I get replacemnts items and I usually tell them I get everything from WALMART-LOWES-and AMAZON.com haha...
AMAZON has become my old Sears and Roebuck order place. Seem to have almost any part number you can type in and shipment is free for all orders over $25. My items usually comes in two days - three at the most....
LOWES hardware and cabinet shops has it all... I'm getting pretty good at making their wood products match the trailer decor.... About the only wood products I could never find at LOWES was the one-inch strips the trailers use for studs in the the walls. ALways have to cut down a two-inch strip...
Works for me
