    I plan to upgrade my 10 bolt non-posi unit with an Eton limited slip unit. Summit Racing has several, but I'm not sure which one is right for my axle housing. I have and want to stay at 3.38 ratio. The unit is stamped 3725899. There are different ring/spline sizes. How do I figure out the right one for me?

    Look at what was offered new in 1962, and follow those specs. I assume you're only cruising your wagon?
