Had an extra set of hands and it went a long way...
Full can of cutting oil, constant stream during the drilling process.

Mine was off by 1/8" on a couple holes, I had someone hold it flexed in place whiles I screwed on the cover. Unfortunately when I got to the VERY VERY last hole (right next to the hitch) There was no more flexing and it didn't line up.

Only took 1 Bit, and 1 can of cutting oil.
