Had to tighten the nut a little more to get the plate to line up, then put a shortened transfer punch into one of the threaded holes and hit the plate. There is enough play in the fit over the hex that I did not try to transfer the second hole, I will do it by dimension. I brought it back home to drill.
I have seen a drawing of the part that shows two holes, can not find that drawing anymore. It is really small in this drawing, but you can still tell there are two holes. Number 59.
how many of #63 the bolt does it call for.
