Oil pump/stud interferance

Other than removing the stud and re-using the oem bolt, does anybody have ideas to use the stud and still clear the pump? I was thinking of trying to remove the stud. put it through the pump, start the washer/nut and then attempting to slide the whole enchilada down and into the block. Comments, other suggestions? Thx for any and all help!
I wouldn't go through the expense of having the cap machined. A bolt is more than enough, it's just a oil pump.
