1984 Olds Cutlass broken oil dipstick tube

Hello – I’m not 100% confident on the year of the car, it’s my friend’s car and believe it’s a GM 327. Today he went to check the oil on the car and the oil dipstick tube broke right at the base of the tube where it goes into the engine block. Looking for a smart, inexpensive, safe way to remove the old tube to get a new one installed. Appreciate any of your tips/tricks/suggestions as I’ve never had to deal with this before.
