The Pro also had longer rear shocks, different front tower for the longer fronts. A rear tower spacer to flip the rear shocks behind the tower. The kickup is different on the longer chassis, the Pro buggy version had a cutout for a large servo saver. Longer rear camber links for the H arms. Front bumper, or at least a different one, can't remember. Think it had the "pro diff", a bearing in the center of the diff gear. Different battery holder with a more durable hinge.

Might be obvious, the bumper and white rod ends are not original, nor the pink springs. The pinks look like later Losi thou. The Pro came with those rear X pattern tires I think, but if I remember they were available before the Pro.
