Yes and I, once again, figured GM put millions into designing the Astro steering system and lots of guys have used them. When I was at the junk yard I picked up a newer Trailblazer shaft to. It has larger joints and takes a larger shaft, my plan is to use it if I have any signs of fatique in the Astro set up. I have also seen where off road guys used farm implement universals too.
