Funny thing ... I was at my favourite auto wrecker about a month ago and asked what they do with the owners & maintenance manuals. I usually look in the glove box and I have never found one. I thought they might store them in the building some where. Nope ... they throw them out! They told me they didn't think anyone wanted them.
That's way cheaper than what I found for one on eBay. And I bet it's a brand new one too.https://www.techauthority.com/en-us/products/81-326-0255
this is the cheapest I've found it online. You could also try calling Davies Jeep and see if they have a copy from all the parting out of Jeeps that they do.
