Is the steel in a K5's frame heat-treated?

    I bent one of my tow hooks, and wanted to heat the little part of the frame up and pound it back flat. If it's heat treated though I assume I couldn't do that. Thoughts?

    That will probably work but it will be weaker than before and you will probably bend it again. If you have bent it once you should probably reinforce your tow points.

    It should only be weaker if indeed the frame is heat treated. It's not so much bent, more like "dimpled". The bolt through the frame has started to pull at the nut on the other side, creating a bulge and a gap between the tow hook and the frame. [Of course it took running over a 2002 Grand Prix to do that!]

    The resto info lit pack that GM sent me on my 85 just says the frame is made of Carbon Steel with a tensile strength of 36-39,000 psi (section modulus 3.14).

    Mild stamped steel...go ahead and heat it, you're not gonna hurt it.

    I wish I had some. They towed the car away before I could get hold of a camera, but I did try. The lady was going to turn and so I didn't slow down much assuming she would go and I would roll on by. Instead, she changed her mind because there was a car coming from the other direction, and suddenly stopped dead. There were 3 maple trees about 1' from the road edge on the right, the oncoming car, and the Grand Prix in front of me; I figured that was the path of least resistance. I hit her at about 20MPH and crushed the back end of the car to about the rear axle line, and pushed it about 15' (it was wet out). The insurance company totalled her car, and all it did to the [K5] Beast was bend the driver's side tow hook down 1" or so, and the spoiler broke the glass out of my Hella 5000 lamp [mounted in the grill]. I was kind of pissed it broke the glass, because no I have to get a new lens/reflector assembly for it. I ended up with one of my 40" Boggers on top of [what used to be] the trunk. I guess that will teach her not to make sudden irrational movements in traffic, and me not to follow so close or trust bad drivers.
