Has anyone successfully used the USCartool A500 Crossmember?

My bad, it wasn't clear to me til I read this response. Every car is just a hair different, especially being that we are modifying the crossmember ourselves. Ssome cut out more than others, some are lowered, some have SS springs. So they leave it unwelded for you to set your angle where you want, and tack in place. Check it, re-check it, weld in in place

Right. Should I wait until the Driveshaft is made before welding that tab on? What the beat way to check the angle?
