Install a Hurst Pro-Matic 2 under the stock console and dont look back. Youll have to cut off the old mount down to tunnel. Even the Hurst ball looks stock. Only thing that is different is the HURST on the shaft externally and the lack of stock ball side inserts but you may be able to tap and thread the old ball and screw it on too. IIRC the console ashtray wont fit as there is a shifter piece right there. If you can get the cable travel of the original to match the lever travel of the later 904, you can do it.
