Matco installation with Planearound spacer

Finally at the point of installing the wheels. I purchased the planearound spacer to repalce the 3 spacers that are supposed to be fabricated for the wheelpant bracket. MY question is:

Did people just use the planearound spacer? Its 21/32" just like the instructions call for. But the Matco instructions have you add small spacers to the original 21/32" spacers you were supposed to make. This certaily causes the known interference with the AN fitting. Are the additioanl small spacers needed for proper wheel pant alignement?

I don't recall if I used the matco spacer with the plane around spacer. I did however had to clearance the bracket for the an fitting.
