Vibration after 9” install - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I just installed a Gforce 9” kit in my 2015 1LE. So car has new rear end, axles, and driveshaft. Driveshaft was built by a local shop, its a 1 piece steel. Now I have a vibration coming from the rear. It shakes the back glass and rear view mirror. I have flipped the rear ujoint 180°, rotated the front adaptor of the driveshaft (Sonnax T35-GMFD-01K) nothing I did really made a difference. I also swapped tires from another Camaro which didn’t seem to help either. All of the suspension is tight, no play in wheel bearings. Is there something I’m missing?
