can't figure out Thule roof rack

I bought a used topper a few weeks ago with the track system. He gave me all the accessories but I can't figure out how the bottom part of the Thule roof rack system mounts to the topper. If someone knows please try to explain or pictures would be very helpful, thanks.

 

Can you up load or send me a picture?
I should have no problem advising you, but there were different versions and set ups.
If you can send a picture of the gear provided, I will get back to you.

Here is a link to a thread that uses what should be the same system you have. There are some great photos in it.

Also, check RackAttack or Rack and Road. Both of theses sites will show the type of equipment that goes with the setups.

 

sorry this took so long but these are the pieces to the bottom part that i can't figure out out that mounts to the tracks on the truck.

 

I just ran outside and took pictures of mine. The quality is terrible, hope it helps.
Unscrew end cap on the track.

slide the feet into the track.

tighten feet down

attach base
