Looking at dark ass pictures, of a diff wont tell me what they are for. As a matter of fact I have a s14 diff in my shed and I couldn't tell.
Not only that, there are plenty of cars that tomei makes 2-ways for. I had one In my Rx7, but that doesn't mean this would fit it.
You need to list information like that when you list something forsale, take your ass back to florida drift and fail some more.
