Here's some links to the various heatshields. Since it's not a restoration it can be any style. But you have to have one on a Pontiac with headers or ram air manifolds. (a Chevy heatshield wont work since it's on the opposite side of the car)

On the Gramma car, I used the factory solenoid shield. You can also use the entire heatshield wrap for added protection. The more protection, the less the problem (Pontiacs with headers and/or ram air manifolds are notorious for cooking starters).
Here's a photo of the factory style heatshield on the Gramma car with ram air manifolds. See how close that manifold is to the solenoid?
And also here's a shot of the bracket that routes the factory starter wiring on the Gramma car.
