[07silveradoVA]

Hey guys Im trying to get my 2nd row bucket seats out of my 2005 yukon XL to replace the carpet and I am having alot of trouble removing the back set of bolts, it looks like i don't have enough clearance to get the nut off the bolt, any help is really appreciated im trying to remove the passenger side seat and i have three of the 4 bolts out at this point.
