I think I have the wrong rubber mounts

I've been fighting a vibration issue see my other thread. So I leveled out the car on ramps. (Confirmed with level on sill)

I went to check my motor level and it's not. Ugh. I then looked at my mounts and they are different passenger vs driver. I'm thinking I accidentally used the conversion mounts (/6 to V8) when in fact I have a biscuit V8 k member.

Should the rubber mounts be the same on a V8 340? Also how to tell if I have the metal brackets on the right sides?
