window channels need.

I have two sets of window channel sets I need. The first channel is a 2720 bsi. It measures metal to metal 28" long. THe second channel is stamped 2130 bsi. It measures 22" long metal to metal tip to tip. I am also in need of the plastic stops that go at the top of the window. They are black plastic u channels. They measure 6" long and 7/8 wide and 5/8 deep. I sent different pictures of the window channels themselves beause I wanted to make sure you could see the boots on each end of the channels.

I really appreicate your help on these and will be glad to answer any questions you may have. Does the window channels come with the end boots. I hope they do and are rivited on so I do not have to install them.

Thank you.

I checked out the boot and the 2720 bsi has the 15-004 boot and the 2130 bsi has the 15-005 boot and I need a pair of each. Were you able to find the plastic stops I questioned about? here is a picture of them

I am getting ready to order the window channel s 380 22 and s 385 28. You were not sure of boot used and I responded that the shorter channel took 15-005 and the longer one took the 15-004. My question is will the boots be installed on the ends of the window channel or do we have to install.
