Salvage yards price varies with the location and the weather. Your friend ship with the owner or person dealing with at the counter. Weather or not they are getting any and the current scrap price. Not to mention if its a you pull it yard or they pull it.

Anywhere from 25 to 250 bucks is a reasonable price range depending on any of the above and more.

With only 22 inch tires a car diff may be over kill unless you plan to literally try to pull logs with the creation. All sorts of Quad stuff in a drive around buggy should be fine with 22 inch tires as long as the weights not major heavy.
