Good luck finding one. Been looking for a running one for 10 years. Try call the Parts Place in Auburn Hills. Here is there web site. http://www.partsplaceinc.com
They may have one but if they dont they should be able to find you one.
Another Option for you is to find a 1600 and have it built up. I dont know why but the 2.0s are costly to have rebuilt. I looked at an 1800 that was turned into a 2160 (os some shit like that) and it was going to cost the same.
Good Luck. Also Got any pics of it.
