I chose to start out with a sharp .107" diameter bit to make a pilot hole. Using old motor oil to lubricate the bit and not to burn it up:

I then chucked the new cobalt 7/32" fractional and drilled the final hole. A # 3 bit could not be found after looking in three different stores.

I prefer to add a dab of anti seize to everything.

Two new fittings in my rear lift. All done and now will prep for paint
