Dont know if this is anything you would want to make or not. But I need a 1/4in thick spacer to fit between the hub and the steering knuckle so I can do the WJ brake swap on my YJ. You can put the late model knuckles off a WJ grand cherokee and get larger better brakes. But, in order to bolt everything together you need a 1/4in spacer between knuckle and the hub to make it work on older model D-30's Here is a pic of the flange
here is a pic of the knuckle with the spacer welded on.
The only place that makes them (that I can find) wants $30 each for them, I was wondering if you guys could make them any cheaper. Like I said, I dont know if this is anything yall would want to do or not, but I figured I would ask.
