Arne, Thanks for the information. Can an early model 240Z shifter be modified? Do you know where I can obtain an existing modified shifter? There happens to be 5 shift levers on eBay right now for about $20 (see item # 300267695928). I'm tracking down a 5-speed. Will the required modified shifter for the 73' tranny and the 5-speed be the same? For either the 73' or 5-speed will the tunnel opening have to be cut and by how much (to the rear or front)? Sorry to throw back so many questions but any help would be appreciated. Thanks. Robin
