The frame tabs should fit the frame. If you are inclined to put them on there, match the body mount to the frame tab. In other words if the first tab is from the old frame use that model bushing. If the next one down the frame is a new one, match it with a new bushing. I haven't ever done this, so I have no idea what the results will be. I can go look at the 87 vs 73 frame, but since you have the same you could do that also.

I would check to make sure that the bushings are going to mount with the proper spacing, and that the mounts are going to mount correctly also. I don't "think" the mounting location is different, but the bushings are.

Am I rambling......
