coloradostang 10 Report post Posted June 13, 2013 Swaped out the old FMX for a C-4. Having trouble with the shift pattern. Do I need to modify my fmx lingage to work on the C-4? I read somewhere you have to drill a new hole in the shifter bracket. Also I need to know where the bracket on the tranny should face, up, down, it rotates 360 degrees when loose. There is a vacume fitting towards the bottom of the tranny, where should the hose run to? And finally anyone hooked up a kickdown cable? I have a quick flow carb and have to use a cable. Got the cable no directions though. Thanks. Quote Share this post Link to post Share on other sites
