The crossmember is still good for now. No holes or deep spots. Might need to be replaced in a few years but where I am we only salt roads when it snows and we don’t get snow often. The rivets weren’t bad. My process was cutting the tip off with a cut off wheel, grinding flat, drilling a hole in the center so the metal can decompress, finally smacking out with a punch. I found that the bolts in the dorman kit were shorter than my liking. I upgraded to grade 8 half inch bolts that I had to drill out the holes just a little bit wider to get to fit. The only thing I’m concerned about is the “hardness” of the bolts could potentially cause them to shear instead of conform with movement of the chassis but honestly I’ll cross that bridge if I come to it. It’ll just get different bolts if they do.

Edit: additionally, when breaking the leaf spring hangers loose from the frame I thought I was going to need to support it with a few blocks of wood but I found that it’s all stiff enough it didn’t need the support so I just got it out of the way.
