Cable clip question

That is one clip, front and back view. There are 3 cables, 3 mounting brackets, and 3 clips. There were no screws. Hope this helps. When this is done, I'm going to try and copy all the posts on heater boxes, cables, heater cores, fiber glass repair, into Word and make a mini-book. You all have done excellent work and have provided really good info NOT in shop/other manuals but is so needed.
