Vic aka (Old Skool) should be chiming in here. He will probably have every thing you will need. Trans, linkage, cross member and knowledge to help you get it done. He can even take your 3 speed column and swap it over to the auto for you. He is busy so he may not see this right away so you may want to search the forum and when you find a post from him, send him a PM. He's a good guy to deal with.
