Base open diff to factory vlsd swap

Hypoxic

First if all, I know that I should save my money and buy a real locking diff. Thanks for the input, but please save your typing. In the mean time, I have a factory vlsd laying around and I'm going to put it in my base Z. Problem is the vlsd is missing the stubs. Don't ask me why, I don't know. Can I just swap the stubs from my open diff? Do I need a different size? And if so where the f can I find one? Any help would be appreciated. It seems every thread where someone asks this question gets hijacked by everyone telling them to get a real diff and the original question never gets answered..
