2008 Yukon Denali. I'm not sure what the part is called, but it just wraps around the base of the seats, and it's plastic. There's a piece that clamps in to the seat part to hold it in place. I circled it, the part is broken so there's nothing that can go into the seat to clamp on. I've attaches some pictures. Any suggestions on how to get base part to clamp back on?
