Longitudinal body members, especially the right side, around the jack points.

The inner "ear" where the right-rear trailing arm mounts to the chassis. The section of longitudinal in the right-front corner of the engine bay, where it turns to go up. (AKA the "hell hole".)

It is much less common for 914s to rust around the torsion bar mounts at the front of the front suspension, but it's certainly worth checking there. Early 911s are notorious for rot there.

It is also less common for the outboard mount for the rear trailing arms to have structural rot, but that's still an important area. (Tip: When you get the car, pop out the plastic caps on top of the three bolt holes on that outboard mount and put as much PB Blaster or Aero Kroyl in there as will go in there. Those bolts love to rust in place.)

A full cage should help with the longitudinal stiffness, but having a sound body is always a good start.
