On any modern race platform that starts with a stock body, it's important to pay special attention to all of the suspension pickup points or mounting brackets. Starting in the engine bay, our first concern was the shock towers. You want to verify they're in good shape, with no deformations or signs of fatigue. On early body Mustangs (pre 1970), these are notorious for sagging, which destroys alignments and severely affects handling. Luckily, most of the late-model cars show no signs of sag, as was the case with ours.
