So I also looked on ebay for some a arms and found this set up.

If I need to I can probably fab up my own. But I understand about the pointing to center too. I was curious about that before.
I got my rear hubs today, sitting on the porch. Hopefully I can make them work if not can resell them. they are off a DS650 bombardier. $15.00 + $12 shipping.
