Dipstick tube plug in block (removal)

Hey there, have a 63 dart that I swapped a slant six out of an 85 pickup into. I had to switch the oil pans but didnt realize until after installation that the dipstick tubes are different. So currently I have a plug in the block by the motor mount that need to come out. I tried with a vise grips to get a grip on it to pull it out but didnt work. Any way to get that plug out without taking oil pan off and drilling? If I drill a small hole to put a screw into for pulling will it drop metal shaving into the lower end of my engine and potentially cause damage? What is the best/easiest/least time consuming way to approach this? Thanks:coffee2:
