Mine were welded on my 70, I couldn't under stand why the bolts didn't budge when I tried to remove them. I said to myself, why would these be left hand threads, then I looked closer and noticed the welds. I used my Dremal with a thin cut off wheel and put a cut into the weld and then used my 1/2 " impact with a impact socket and busted them loose from the sheetmetal.
