Is there any visible objects differentiating the two? I’m trying to figure out exactly what I’ve got but it’s almost impossible to decipher without any previous knowledge. Any help would be greatly appreciated. Here’s some pics of it and from what I can tell the outer housing is the same if not similar to a Kaaz diff. ![http://i265.photobucket.com/albums/ii211/get_sideways/Other/IMG00081.jpg](http://i265.photobucket.com/albums/ii211/get_sideways/Other/IMG00081.jpg) ![http://i265.photobucket.com/albums/ii211/get_sideways/Other/IMG00082.jpg](http://i265.photobucket.com/albums/ii211/get_sideways/Other/IMG00082.jpg) ![http://i265.photobucket.com/albums/ii211/get_sideways/Other/IMG00083.jpg](http://i265.photobucket.com/albums/ii211/get_sideways/Other/IMG00083.jpg) Thanks Mike ---

I believe that if there are 2 notches visible in each hole in the carrier, then it’s 2-way. I have no first hand experience, just a convo I had a while back with a buddy of mine. He bought a Targa car and found out that it had a TRD 2-way when he was scrapping the rear end. ---

2way. The holes inside show a full diamond. If it’s not a diamond and some weird ass shape, its a 1.5way. ---

No, all 2ways have the same diamond shape in the circle opening, which is around the diff casing. Sorry, no pics saved. I did my research years ago and I just remember the difference. ---

1.5way is perfect for the track, for drift 2way is the best! ---
