You have to weld the headset part to the mounting tab ... and you're supposed to get the angle just right by visual, a straight-edge, and a prayer. Because you are gestimating that everything is lined up properly while you hold your thumb at arms length and go "uuhhh-yup!"
Anyway, after welding the hole closed and filling in any other gaps ... it looks somewhat like this ... in desperate need of the grinder. That poor grinder wheel is just about worn down to a tiny nub. I'm going to have to buy another one soon.
This is what it looks like after grinding.
I agree. Nothing that some bondo and covering it up with paint won't fix.
