Dipstick recommendation 225/6 '72 Dart Custom

My '72 Dart with 225 is out of the U.S., and I noticed when the car came back from the mechanic (maybe 3 weeks later was the first time I checked the oil), that my dipstick ends with the words "DO NOT OVERFILL." In other words, the second "L" in OVERFILL is where my dipstick ends. I guess it got broken off and the end is laying somewhere in the oil pan. I need a new dipstick. There are various ones on eBay. Can someone tell me whether all of the ones in the link below will work, or which one will among them? I just need to order the RIGHT one and bring it back with me when I'll be in the U.S. It's an extreme bummer to bring back the wrong parts.

Or alternatively, if I just fill up to the last trailing L is that dangerously overfilled, or maybe it's pretty much fine? I have no recollection of where the fill marks were before the dipstick end broke off and so when I added 5 quarts I still couldn't get it to reach the "L" but the engine seemed very happy and had been occasionally been making some noises when the oil level was (perhaps dangerously) low.
