New member here. Recently bought 68 mustang coupe with 289. 2 barrel, ps, pb, auto, a/c. has new dual flowmaster exhaust and new 17" chrome wheels and tires. i need to do some work to it such as stiffer rear suspension. any thoughts on how to beef up the rear suspension? as it is now with a person in rear left rear wheel can scrub. also want to upgrade carb to a 4 barrel. and possibly a little hotter cam. here is my question what do you guys reccomend in the way of carb and intake and what about a cam? and the rear suspension. all suggestions greatly appreciated.
