A:

1st I'm sorry I took so long to respond back to you. I found this item in our warehouse, and took a good look at it, there are 2 long tabs (2 inchs maybe) 1 is the front and the other is in the back of the helmet, not sure which is front or rear, 1 has a velcro strip and the other has some holes. These are only things you have to attach to your helmet,there should be the oppsite side of the velcro and there should be what I'm calling plastic buttons that fit into the holes. You can adjust how high the helmet fits on your head with these 2 items also. If you don't have the helmet side of these to attach replacement liner to, you might need to purchase a new complete inner skull and liner system.
