I am dropping in a 460 and a c-6 trans in my 70 cougar.I have everything for the swap except for the c-6 floor shift linkage.I also have a console in the car and don't know if I can change the factory floor shifter.I do have the linkage for the fmx trans wich will work on the shifter.should I just fabricate the trans end of the shifter rod?thanks,randy doing swap next weekend.
