I have the triangle heat shield on the rear bulkhead and the heat shield over the muffler. Is there an over-the-axle heat shield for 92s?

I think it is this piece...This is from and 87 being sold on eBay. My car is/was pretty original and wasn't missing much. However, I don't think this piece was ever on it. It did have aftermarket exhaust so someone might've removed it when they did that install. I have a LS1 plastic tank now and don't want it to melt or worse.

 

I think this is the one I'm missing...Was never on this car.

 

The heat shield that is most important to protect the fuel tank is the large one that goes above it. The area you are looking at looks like the one that goes above the axle portion of the I-pipe.
