Damon,
the cap and quarter are spot welded together. There is a small flange on each piece behind the seam you can see from the outside. No real easy way sorry to say. I have remove the two as one piece. Then I drilled out the welds on the flange if you need to.
Some one May have a work around but I didn't find one.
I really can't remember if the front of the qp and rear of the rocker are welded but I think so.
