ya seats can be a pain.i took out my factory leather ones for a few months for racing seats and those brackets of course didnt fit aftermarket so i was only running 2 bolts in both of them.unsafe so i took them out and sold them and put my factory ones back in, and even those took me FOREVER to get back in?! someone told me to get A front bolt in,then A back bolt kinda cross bolt it like wheel lugs. but a lot of tuggin and pullin
