Steve, I just sent over today the photos of the rear mounts. also the original rubbers. the mounts in the RG&JS are the one on AA4343, they should be in your Email.
I have everything you need to install the multi disc I have rebuilt clutch packs, rebuilt trans both early and late cases rebuilt bellhousing , smooth and rib pedals also flywheels. I think there are great 5 of my vehicles have them. they last a very long time. let me know if I can help you.
