Question about rear suspension bushings - with pic

Ok, my driver's rear is now a mess. I went to take the strut bolt out and it snapped. So I was forced to take off the entire rear knuckle assembly to get the bolt extracted. Well as I was taking off the rear knuckle, the bolt on the bottom was permantly seized and was forced to cut if off. I'm talking about the bolt where if you look at the rear knuckle, go to the very bottom of it and there's a control arm that bolts to the bottom of the knuckle. When I cut it off, it ruined the bushing. I don't even want to know how much the dealer charges for a new knuckle, so I was hoping 1) I get the strut bolt extracted and 2) the bottom bushing could be replaced. I looked into the polyurethane bushings for the rear and could not find any information about the kits coming with this bushing.

Does anyone have any experience with this bushing kits? If so, do they come with the bushing that I need?

Here's a diagram of what I'm talking about, it doesn't show the bushing but I circled the area in red.

I'm hoping these kits come with these bushings (1 for each side) so I won't be obligated to go to the dealer.

Thanks for any help,

Steve
