I am not sure why but the PO of my car cut out the front trunk floor pan in my car-- I suppose he was thinking of putting in a GT oil cooler. I am looking to replace the front floor. If any one has a fairly decent front trunk floor pan- please let me know. I pirated a pic from the internet and marked in red the approximate area that is cut out (I have a bunch of stuff piled on my car now which means I cannot open the front lid).

More than likely, it had an air conditioning condenser mounted down there.

They typically mounted a dryer unit inside one of the front wheel wells too.
