Default Vibration on decelaration

So I have this vibration problem after making a run during deceleration.Had same problem under high speed acceleration vibe started about 100 and got real nasty at 130, found traction bars were too close to frame and would not allow pinion to raise enough to be parallel to trans -3 degree down position.Im thinking about installing 2 degree shims under spring pockets to raise pinion,but then traction bars will be too close to frame again.So would i have to install another set of shims to get bars back down ?Iwill need the bars to keep pinion from going too high during launch?Any thoughts or tips welcome.also good place to get wedge shims that fit 76 ta

I would pull the driveshaft and flex the u joints to see if one is hurt.
