I don't know if the covers are the same or not. Is it notched on the bottom of pump mount for the balancer? because the plate needs to be.
let me see what I can find out.
Took the pump and extension off and I see that the hex drive is almost flush with the outer cover. If my straight edge is right I have .016 between them, so we can just go flat with it. I'm sorry, I should have pulled that off before I started asking questions!
ops:
I'll see if I can find a pic of the weiand cover somewhere
