Vibration right off idle

Thank you. I'll re measure at the pinion yoke tonight, to confirm measurements. I have an A500 so it's not stock, but the mount is new.

I'll see if I can shim the trans up. When you say you had both angles the same +/- (trans up, pinion down) was that at rest or calculating the pinion rising x degrees under load?
At rest on my 4 post lift with the weight of the car on all 4 tires.
Try to keep the angles between 2-2.5 degrees and you should be good to go.
