Just went through this and wanted to share how I did this.
I removed the top bushings with a ball joint remover and went to napa to find something close. What I found is 267-4492. It's the same type of bushing width and bolt size are the same but it's a hair bigger. I used a cylinder hone to get the hole a little bigger. About 0.01 and then was able to press in with some heat. Will post pictures of sizes. Picture of bushing installed down below
