bad vibration in entire frame

LOL!!! Funny man!!!
The motor and tranny seem fine. Looks like it happens more significantly when I am slowing down without brakes - just kinda coasting down from 60 mph. Happens at hard boost as well. I'm relatively sure its some small shit, thats all. Just driving me nuts with the vibrations. LOL!

Is the vibration speed sensitive? If you're doing 60mph and feel the vibration, can you push the clutch in and get the vibration to change or go away? Engine RPM sensitive? Does it feel like a missfire? Does the vibration start at 5mph, or any certain mph? Details please.
