Help with Lower Control Arm Replacement (and squarebody arm compatibility)

[jsera]

Hey guys,

My 72 has a bent passenger side lower control arm needing to be replaced. I am having some trouble locating a new one readily available as the truck is at a shop and I don't want to cause delays (ecklers has the arm but its on a 3-4 week back order).

I read that the squarebody arms are the same fit, but that I would have to install 72 model year ball joints to play nice with my spindles. I am also of the understanding the only other difference is the bushings went to rubber on the square bodies. Is this info correct? It seems the 73+ arms are much easier to get.

Alternatively anyone know of a vendor that sells an oe replacement for less than $120?

Thanks!
