Bump......FYI, I check Amazon every few months and I just discovered these upper 4wd A-Arms are available again (1st page of this thread). They are $59.95 (right or left) and they had 6 of each. I just bought one of the rights, so at the moment of this post they have 5 rights and 6 lefts.

Ebay has them too...........same price with free shipping. Tim
