I have the rear end kit. Everything fitted in fine, albeit the diff needed a little "persuasion".
But still waiting on axles. Basically getting the exact same runaround you are.
I've called, texted, emailed, facebook, instagram and still getting nowhere. Last I heard I was getting them by end of August at the latest - but no go.
I'm at a point of looking for a partial refund and getting the axles specs to someone else.
