The Pacer IFS is nearly perfect for an AD and was the #1 choice for years. It could be either welded or bolted in and the factory cross member could be retained. If it has drum brakes it is a 1975 as all later ones had disc brakes. If it needs rebuilt one can use Ford disc brake parts, Chrysler lower ball joint and Monte Carlo upper ball joint. The caster/camber ecentrics are the same as Chevy pickup so unit can be rebuilt to new but tweaking (some major) is needed. "We be Old" is a frequent poster on the BOLT and has an AD with the Pacer IFS so help/advice is available.
