steering dampener choices for older quadravan

[johnboy]

I have a dana 44 out of a 76 quadravan under my 86 diesel van. I am in need of a steering dampener but not sure where to begin looking. I'm pretty sure the axle is the same as a 75 ford truck but it has chevy parts on both ends. Hoping someone out there can throw me a part # or a brand I should be looking at?
Also wondering if anyone has come up with an easy single tracbar setup for a pathfinder with the undesirable dual tracbar setup? It feels like I'm driving a backhoe.
