318, 340 or 360 motor mounts

I am in desperate need of a set of motor mounts for a 67-72 V8 K Frame. I just got my car on the road and there is a terrible vibration. Turns out I have the wrong motor mounts and the motor isn't sitting level.

I have read so many threads about the difference between 340/360 mounts vs 273/318. All of it makes sense, but I am having a hard time distinguishing them by pictures. I am already $85 on the set that I got and they aren't right.

Thanks again.

I see you have a 67-72 V8 K frame ?
What engine is going in ?
67-72 V8 Kframe with a 340.

I'll take whatever is out there at a reasonable price. If they are 340/360, great.

If they are 273/318 that works too.
