Unfortunately, by the time you got through with shipping, the price of the part and my markup (to make it worth my time), $30 is about what you would spend (depending on what I have to pay for it). Plus, I don't have one "in stock" and would have to find time to go get it. If you can get it off E Bay for that, it's not a bad deal if it is in good shape. I would just do that unless you can get it locally.
If it is a stock 1985, it should have the burl walnut grain. Be careful when buying one as in 1986 or 87 GM changed the grain and it looks very different. Also, try to get one with the chrome paint in good condition. Using silver paint to replace it will not work as well since the paint most people use (Testor's paint pen) never dries completely and tends to smudge.
