Ball Joints and the Rubber Boot

[Nils]

Hello Guys,
I have a new Problem. I would press my new Ball Joints from CPP in my Lower controll arms and dont know if i press the Ball Joint with the Boot into the Controll Arm or put the Boot later over it ? Because the Boot fits perfect into the hole of the Controll arm and on the Boot is the text: Mount Inboard.
The second Problem is, that a have two different Ball Joints. I think the small one ist the right one. The Numbers at the bottom are the same. Please can you help me ?

Thanks a lot again

Greetings from Germany.
