That is one of the reasons some of the older sets of sockets had lots of 12-points with them. | | | | | Joined: Nov 2008 Posts: 355 Shop Shark | | Shop Shark Joined: Nov 2008 Posts: 355 | but like i said they are some really rusty bolts i think they would tend to just round off the corners

Check at your FLAPS, they might have them. I don't know that Sears has them these days. I don't have any, and generally use the following procedure. Penetrating oil, open end wrench, then grinder,sawzall, or gas-axe. Ahh the escalation of violence. Generally though, Brad is right, they just brake. I work on old wooden boats, and up into the sixties and even later, many of the fasteners are square nuts. Made up at the yards, or bought buy the keg. I'll tell you one thing, if you can find an old keg of the hot dipped galvanized fasteners, they will last virtually forever on your truck, and are much easier to remove than stainless steel if you brake one, and the threads don't gall like stainless on stainless. Of course, this is all coming from someone who not only likes the square nuts, but also likes old slot drive screws, and the Yankee Driver. | | | | | Joined: Nov 2008 Posts: 355 Shop Shark | | Shop Shark Joined: Nov 2008 Posts: 355 | lol really wish there was another option than breaking them, they are on the back side of the dash and not sure they are not spot welded to the back of the dash "bolts that the square nuts are on" so breaking them would mean i would have to completely tear off the entire dash

I have removed a lot of bolts from these trucks and they are the only square ones I know of behind the dash? What year is the truck? If it is the support bolts that bolt will break 9 out of 10 times due to their location and the water that condenses there. The best thing on any of these trucks if you don't want them to break is super high quality penetrating oil like Aero-kroil or similar. Let them soak for a few days before you try them. | | | | | Joined: Nov 2008 Posts: 355 Shop Shark | | Shop Shark Joined: Nov 2008 Posts: 355 | did somemore looking under there today  they arn't spotweld bolts but would still be hard as hell to get a grinder to them :)as far as year its a 39 lol not alot of room to play under that dash
