88 FC Vert Vibration Help

[DaleJK]

Hi everyone so I'm new to owning a rotary but not new to working on them, I recently purchased an 88 vert which vibrates from around 2.5-3k rpm upward whilst driving or in neutral, I've checked the driveshaft u joints and they are okay and the engine and tranny mounts seem fine, what else could it be as I really would love to fix it, thanks guys :)
