Is that an open or limited slip differential? If the former, what LS option are you considering and why? Clutch pack? Torsen / helical gear?

In my case I am building leaf spring car because I want the experience of driving an original type car. If I ever get one of the chassis to the roller stage using original style parts I will try to make parts for the second chassis using parts from easily available cars. I want to do this in a way that if I can ever afford to get a second set of original style uprights and brakes it will bolt on without any mods to the chassis. Not sure if this is possible but it is my goal.

My goal, which I put in my build (actually pre-build ) thread, is to learn about the process of building the car by actually doing it, while ending up with a car that roughly replicates the characteristics of a leaf-spring car. (While looking sexy as all heck.) Since the rear diff doesn't add materially to that experience, I'm willing to economize there. I'm still exploring my options about uprights. I believe I've seen a set of welded uprights.

Those are good questions I haven't asked yet. Though it gives me something else to think about.

The tag number on the diff will tell all.
