    That was my first thought too! It looked like a wood blade. The large tooth version doesn't always work on hardened bolts, it just depends on the specific bolt hardness and metallurgical properties I guess. But they sure as hell saw through everything else right quick!

    Yes, and then use an impact wrench and black sockets.

    I just did this a few weeks ago on my donor truck. I used the Diablo Steel Demon carbide tipped blades in my sawzall. Make sure you spray them with plenty of oil to help keep it cool and lubricated.

    I'd also recommend getting a 4-1/2" angle grinder and some good cutting discs from harbor freight. It's only about $25 for the angle grinder and $10 for a set of 10 disks

    @fast68chevy,

    I had a problem removing the 3/4" bolts on my traction bars last year. They were rusted solid in the bushing sleeve. I cut the head of the bolt off first then when I couldn't push it out by hitting the bolt with a 1/2" punch I had to saw the end of the bolt off just behind the nut. The the traction bar just came out of the bracket anyway and I delt with what was left in the bushings, just fell out by itself. That option is always there where you just start cutting the bolt away until the leaf falls out of the bracket.
    NO FIRE! One slip and there goes a hanger, then while you're there you might as well wash the rivets off the hanger and bolt another one on. Then you look and something is on fire from sparks that got away. Don't do that. Yeah a torch is much faster and hack sawing a big bolt is hard especially when you're up against the frame on the forward bolt, that's when you wish you had used a torch. Just whatever you use make it clean.

    Nothing like a torch but the fire and sparks is just part of the know how when using them.

    Torch, peanut grinder or good die grinder, impact wrench. In that order.
    If they’re really 50 years of froze in rust belt goodness, just start with the “Can’t be tight if it’s liquid…” approach and make the project enjoyable!

    I have encountered a bolt once that my Milwaukee 3/4 impact with a short socket(18mm ) couldn’t even budge the pad WITH the huge ass battery for the chainsaw

    This was defeated by a gm subframe bolt but those are closer to the ground and also vertical and have a bushing surrounding and they held water and debris in.

    I’ve never met a bolt I couldn’t overcome with a full battery
