oil cooler pipe

I have a 94. After having some weird transmission issues, I found one of the hard line hoses for my oil cooler is rusted and leaking. I've been searching all day for the right part but cannot find it anywhere. If anyone knows where I can find it or what I can do you work around it, i'd greatly...

Need to find a very hard part to source bc it’s discontinued and out of stock at dealerships. It’s the Oil Cooler Pipe with part number 15767-50040. Thank you for your insight and connections! Nic J.
