Task Force Deluxe Trim - Joint Clips?

[CMFT]

I know there has been a lot of discussion on the deluxe trim kits for task force trucks in the past, but I couldn't find an answer for one of my questions.

I bought a new deluxe trim kit, but the kit did not come with the joint clips to connect the back window moldings. I have been unable to locate a joint clip specifically for this trim kit, but have found a joint clip for the windshield trim. Will it work? Here is a link to the part:

Is anyone not running a joint clip, just butting the two pieces together?

Any help is appreciated.
