Does anyone have any ideas how to go about finding the old size 36" wire Kennel Aire crates that were 20" wide? I've searched craigslist and ebay but was hoping maybe someone knew of a place or site to find dog show stuff for sale. Thanks.

Try this dog show list, they have all types of stuff on there for sale and you can post wanted stuff too.

Try Central Metal Products. They make a 36 x 21 bench crate (mini fold) , as well as a solid aluminum one. Haven't seen a Y-latch Kennel Aire in a long time, sad to say. Friends and I have mini-fold and bench Central Metal crates that are over 20 years old, of much higher quality than my more recent Kennel Aires or the more common crate brands.
