96 Xpress 300 Shock Bushings?

So about a week ago, I noticed that my rear suspension seemed really bouncy, and something just didnt seem right about it. Yesterday while I was riding, it didn’t feel like it was handing very well either. After looking at the rear end, I noticed that where the rear shock mounts to the swing arm, it looks like the bushing rotted away/broke apart/fell out, whatever. So the rear end is extremely bouncy, and wobbles around a good bit too. I’ve been looking for a part to replace it, but I can’t seem to find any parts online, and even looking at a diagram, I’m a little lost about which one I need. Here are some reference pictures.

Thats what the shock looks like, and on the left side, thats what mine looks like at the moment, just an open hole.

Now this shock is what it SHOULD look like. The left side shows the bushing that I need to replace on mine.

After a quick search, this is the part diagram I found, but I can’t seem to find the part I need.

Could someone out there who’s a little better at this than me help me find the part I need, and let me know how many I might need? Thanks!
