You can use Italeri's LAV-25 Piranha kit #259 as a start for building the Coyote. From what I've been told you do need to make a few minor changes but have no idea what they would be. You'd probably have to do a little research to find out what they are. This kit is listed as OOP, but I would think you can probably still find it on many store shelves.
Happy Modelling and God Bless
