Well, you don't want to be beating the shock into the correct shape so
I'd suggest grinding off the offending portion of the bogie arm.
Not sure why I didn't post pictures of that but there's not much to it
assuming you have the right tools to grind cast iron.

Like Kelvin, I ground off the lower lip under the shock mount hole on each boogie. I used a cheap harbor freight angle grinder from Harbor Fright... but an expensive grinder should work too...  It takes longer to get to remove the parts than it does to grind the lip off. But if you are already installing new shocks... just add about 5 minutes a shock.
I would not worry about the change structural strength when "loosing the lip." The boogies where changed during the 1975 changes to an indented edge... almost a mirror image of the earlier "lip" edge.
You only need to grind the edge flat to clear most shocks.
