I used a poly mount on the OE Z trans and the vibration was insane so i went back to stock. Try modding your OE rubber trans bracket to fit and see if the issue goes away. If it does you can rule out the driveshaft.

If you still have the vibe. the next place to check (unfortunately) is the flex plate. Being I'm not boosting my Z I kept my good condition OE in place during my VR swap.
So I'm starting to notice a trend with you, FrankEtier, and every other post I can find, saying that the Godzilla driveshaft should be fine as long as its balanced, so now I'm leaning more towards my trans mount situation I have. It seems like most people when doing this swap opt for modding the OE mount, I just thought it would be more plug and play for my shop if I provided a whole new mount, so maybe I'll start with that. I really hope it's not the flex plate, as I haven't seen to many people complain about this issue with that, and its expensive lol. I'll get in touch with them after the weekend and see about modding the OE mount to see if that fixes it. Thanks for the insight into your swap, I'm glad you got your vibrations sorted out! It gives me hope!
