I am aware of the two shields underbody, the exhaust shield and the one close to it under transmission.
Browsed through the parts book and a few vendor sites with little luck, did the cars have shields where the bulkhead goes over towards the transmission tunnel? I have seen photos of some sort of aluminum sheeting being installed here, original, aftermarket? (the area outlined in red)

(Borrowing and modifying a photo of bulkhead from internet, please dont sue me... I like your site, good work) :)
