I probably wasn’t clear - I have a 98 myself, and I know for a fact that they do sell the bushings alone - about $35 for the bushing alone, so you can actually buy just the bushing (maybe not directly from Toyota, though).
For the DIYer, buying the whole arm with a bushing is generally the best way to go - no need to push out the bushing, just pop the old arm off and the new one on. 3 bolts total, maybe you have to use a spring compressor to help get the ball joint end free… Its not a hard repair. Total time should be 1 hour, and even if you had to buy the whole arm with bushing, the cost shouldn’t be over $250 (part+markup+labor)… $1200 is just obscene…
