I just drew three large circles on the bulkhead, center line bisecting the existing holes, inner line, outer line, drilled my new holes and used a rat tail file and filed to the lines to make an arc between the holes.
My spinner remained true. Not sure how it could get out of true at the front bulkhead. The backplate is pretty stiff and there are a lot of screws holding the spinner to it. You would have to force something, not even sure you could.
Mine where out about 1/4" final slot length.
It took no time at all to do this.
