I totally apologize for the blurriness of the pictures, but I took my original '88 steering rack with its original bushings, and compared those bushings to these new bushings. I didn't remove the bushings from the rack, so the comparison isn't great, and no test fit, either.
Yeah, my steering rack is in poor condition. I'm rebuilding it, which is why it's out.
Both sets of bushings:

This is the passenger side bushing. It has a bit different design. I'm not sure if the '88 needs the other design or not, but the big surprise was that where the old bushing was rubber, the new one is poly. Notice the tapered edge of the original.

Another view of the passenger-side bushing.

The driver-side bushing. Both the new and the original are rubber.

They appear to be identical.
