Ok, well I failed at my original goal to remove them without wrecking them, but they are off. I think it would be possible to get them off without damage by pounding the studs out of the frame. I tried doing that, but the studs didn't want to budge at a level of hammering I was comfortable with. Instead, I welded one end of a wrist pin to the spacer and welded a nut to the other end of the wrist pin so I could use a slide hammer to remove the spacer. Not the most efficient process, but it worked, and it was clean. Another option would have been to cut the spacers with a Dremel, but I didn't want to risk damaging the crossmember or studs.

I used the original nut and some stacked up spacers to press the new spacer back onto each stud.
