HD Suspension or not

I have a 73 Road Runner, how do I find out if I've got a HD suspension or not? I'm replacing my clutch and looking to replace the engine and trans mounts. There are two different types of trans mounts. Thanks!

If I remember correctly Road Runner got the heavy duty suspension. I'd have to check to be sure but that's the way I remember it.

All Roadrunners got the HD suspension regardless of the year!

Thanks, that confirms what I thought!
