When I posted my initial impression of using my 1968 Mustang as a daily driver I mentioned the car’s handling leaving a lot to be desired. The Mustang was professionally restored by a reputable shop fifteen or so years ago, was rarely driven, and garaged until I bought it a few months ago.Though the parts had not seen many miles, time had taken a toll. Once I got under the car for a closer inspection it became evident the Mustang’s handling woes were due mainly to dry rotted suspension bushings.
Since that discovery I’ve been working on rehabbing the Mustang’s front suspension little by little, as time allows. I already replaced the strut rod bushings with OE type rubber bushings. I also upgraded to a 1″ sway bar with poly bushings and had the car realigned with Open Tracker Racing’s street performance alignment specs.
Next I took a look at the worn spring perches. There are several spring perch options to consider. Early Mustangs were built on Ford Falcon architecture, which utilize the same suspension setup. Early Falcons were originally equipped with bronze bushings and grease fittings in the spring perches. As a cost cutting measure for mass production of the Mustang, Ford replaced the bronze bushing with a hard rubber pivot. Perches with the rubber pivot are not as forgiving as bronze bushings and bind, causing undesirable handling characteristics at the limit.
Many restorers replace their spring perches with the OE type rubber perches. These are fine for a show car or casual driver, but there are much better options for those of us who like to drive hard. For a few more dollars you can get perches with bronze bushings, as Ford originally intended. And for a bit more than that you go with roller spring perches, which utilize roller bearings in place of rubber or bronze, allowing full range of motion.
