wheel studs have a look

Just started to remove the old wheel studs on my 74 Duster.Not sure if they gave me the right studs or not.I installed 2 new ones they went in with a bit of effort but in the pic the 1 on the right new stud, you can see a little space between the knurl and the hole, the 1 on the left looks like a tight fit.What ya think.Here are the old and new.When i grab the new stud it feels tight no movement,but unsure.the new stud has abn 103 the old has nothing .
