Received a jump seat for 2018 Tahoe PPV that is supposed to fit. When I have it in position it sits too high to get the 4 bolts in. I raised up the front and took this picture...I am point at 2 pins under the rear frame of the jump seat that seem to be holding it up too high. Wondering if I need to try to make holes in floor padding or maybe cut them off? Any suggestions are appreciated.
