If the nuts are on the outside the bolt is against the framerail side with about 1/8" clearance to the frame. It's not gonna go anywhere once the nut is off unless your framerails have access holes in them for the bolt. I never seen an A body with those. If the nuts are on the framerail side the bolt is too long and will hit the back side of the rocker before you can get it out. Remove the 4 nuts on each perch then pry them out of the frame. Once the perches are lowered down then you can get those fwd spring eye bolts out.
