I have ordered my kit, but will not receive it until mid summer. I’m planning to use a rear end out of a 2014 Mustang GT and I have a question about the upper bushing on the rear end. Page 69 of the manual demonstrates installation of the upper control arm to the axle. In the picture, I believe that it shows a Moser installation. I’m curious if the bushing shown in the picture is provided as part of the kit. I’m assuming that if I’m using a Mustang donor, I will provide the stock bushing. Is this correct?

Thanks in advance for any guidance you can provide.
