Thanks for the relplies.
McDave I have some 2016 and 2018. I tried 5/16 on the 2018 because I have some 2016 that came with that set up and they fit all the way down. They didn't on the 2018 and looked like the top picture. They were hard to get on there straight. I thought since they were both size 20 that would work. I use 11/32 on the 2018 and 5/16 on the 2016.
I like the way the 5/16 fit all the way down on the second picture.
I have two saying 5/16 so thats the way I'm trying.
Thanks fellas.
