    If you don't have access to a torch, I've had good luck with soaking the bolts with PB, heating them, letting them cool and resoaking. Try this several times and before getting the right socket to remove them, beat on the head a number of times with a hammer.

    I don't have access to a torch, so how do you go about heating them? The PB is flammable, so I want to make sure I don't do anything stupid..

    gone crazy

    I said that because by the time it's all over, I bet he will wish that he did. LOL

    Get a BFH out and a chissel and cut it out....then you will have to maybe drill the bolt and tap...
    When there's that much rust there is no easy fix and one thing will lead to another when taking it apart.

    good luck slick, it can be done but that core support looks like it'll need some repair when you get the bushing out.

    Here and there...
    If you don't have a blue wrench, do you have an angle grinder?

    Grind/cut the head off the bolts.

    Then, throw a wire wheel on the grinder & at least clean up that rust & prime/paint the support for the time being...

    When I said propane torch, I meant the type you do diy plumbing work with since I assumed most of us have one. Yes, PB is flammable but it burns off very quickly but just don't let the rubber start burning. The heat/cool cycles seem to allow the PB to work into the threads further and break the bolt loose.

    I used to work on saltwater boat trailers and putting a little (sometimes a lot) of heat on it would make the rust flake or pop off breaking it free. I would get the bolts cherry red then let it cool a little bit and hit the top of the bolt pretty hard with a hammer and would "shock" it loose. You may have to do it a couple of times if it doesn't work the first time. Putting the PB on it between times will def. help the situation.

    Go down to WalMart and get a propane torch kit with a bottle of the mapp gas in the yellow cylinder. The new torches with the electric ignition and the bud tip really get hot. Heat the heck out of the nut and wrench it quick.

    I don't know how you Northern boys deal with that corrosion.


    Pack it up, head South. Your Camaro will love you for it.
