Square body bend fix... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

How are guys that are laying frame straightening out the Catalytic Converter bend on the drivers side of the frame? When the truck is laid out, it's got a pretty distinctive lean, that's kind of an eyesore...

I don't know if I can get a sledge underneath with enough force... in my garage.

I have a torch but not sure if the heat will compromise the frame strength... Anyone got any pointers?

I've searched but all I found were guys that said they straightened, but know specific details.

at one time porterbuilt said he made a die, he would heat the frame and use the die to bend it with hammer. give him a call im sure he will know.

Thanks 54caddy. I remember that thread but couldn't find it.

There's got to be others on here who have done this?... I'm starting my accuair install and want to get this done first.

I did my son's truck. I cut a few slits with a cut off wheel on a grinder, then hammered it flat using a large hammer and a heavy piece of steel as a back up. I then welded the slits top and bottom and ground them smooth.
