Q: Diff case

[PiLLLe]

I asked a lots of people and they just confused me
I was told that the medium/big case diffs are those with diagonaly places screws for filing and draining oil and then again I was told that 3,25 diffs came only in medium/big case and now i'm confused. I have 3.25 and 3.91 and they look the same to me

Here's the picture



So my question is which one is it? Small Medium/Big

Tnx

I have never sen a diff like that,so I am going for Big!

Small has six bolts holding the rear cover,medium has 8,both filler and drain are pretty much in line with each other.

The pictures here will show you what small and medium look like:

Where did you get the 3.25 from?

So judging by the photos above I have a small case.

Where did I get 3.25... My friend had it laying around for many years... That diff changed hans so many times that it had more owners than some honda civics:D I welded it like 6 or maybe 7 years ago and it went lost so exact origin is unknown:D

Bummer I was hoping it was a big one so i I could sell it for big money:D

Tnx
