Rear Trans Mount

[Aussie Challenger]

Can anybody tell me what type of rear trans mount I have as the internet suppliers show several different styles, sedan type & round type like a shackle bush. I haven't been able to get under to check it out and don't want to remove until I have a new one. Is there another model MOPAR that will fit?
I have a '79 Little Red Express Truck, it has a 727 trans and 2wd.
Thanks once again for this information.

Thanks for that info, I am using a poly bush on the rear of my Challenger, is the PST one poly also?
