What type of rear end should i go with for a 89' mustang 5.0, for highway gears?
Im trying to get better gas mileage.
if its a 5 speed just keep the revs down, if you gotta auto, do a swap for a 5 speed. Its all about your driving habits, dont mash the gas from a stop and keep your revs low.
simple with a 5 speed you may want to look into maybe 3.73
