I've got a lsd I want to fit but the lsd needs bolt on drive shafts and my current diff is the push in type .
Do I need new stub axles as well as the bolt on shafts or will my existing ones work?
It also looks like the shafts come in different lengths .Any help identifying what I need would be greatly appreciated .

this might help.

Thanks for the info guys, very useful. I think i am going to try the hybrid drive shaft option.
