The pan you need to find will have a sharp drop to the sump. This is so you can have the engine as far back & down as you can , yet clear the rack : regardless of year of car.
Lots look for the Mll pans (I may have one. It was really rusty so no part numbers were on it. I blasted it - no leaks - and painted it to preserve it , in case someone would need it one day. Was/is supposed to be an Mll pan)
This is the one I use:

Expensive for most folks, but worth it in my opinion.
