Google it up man. JDM 7MGTEs from 89 to 92 should be rear sump. As for the American versions I can't remember/didn't find it concrete. Someone here knows it for sure, whether or not they'll tell you is the question haha.
Uh...motor mounts will be different ya know? The main reason when we swap 7MGTEs into our car we need to use our 5M pan and mounts...
I would not any M engine oil pans I've seen rear sump. They're either front sump, or mid sump, like the 7ms. In my 1990 truck, I'll be using a 7mgte pan in my conversion. Clears the stock steering perfectly, with engine / trans, etc, all moved back exactly 5"
