You need to get the top of the knuckle machined flat where the arm bolts to it. If you just bolt to the as-cast surface it'll never clamp right and you'll likely break studs or at best never be able to keep it tight.
Thanks for the info, idk if I can afford to get it machined flat but I'm not planning on using the dana 44 for long it's more of a mock up for a 4 link d60 later, but what if I weld it on to the knuckle, will it hold long enough?
