My bad, missed the 2 piece DS part in OP's post
Assuming the shortened shaft was rebalanced??
Still would be a good idea to check DL angles
Agree poly mounts do transmit more harmonics/vibration as rubber does a better job of absorbing those
Also look for any sounds of "grounding" (exhaust hitting x member or something)
