Hey guys, I was told these were made for the quadzilla. Everything I have found sure looks like them. I bought them as part of a pallet of arms a year or so ago and finally got around to sorting through them. The ball joints are heims just like ASR has on their arms. I am not sure of the taper of your spindles but you will probobly have to get a shim that sets the taper correct. ASR sells them. I am not real sure on the length compared to stock. With the ball joints most of the way in the lowers are 14 3/4" and the uppers are 12 1/2". Maybe someone will chime in about them.
