Vibration under seat

[95GtTopLess]

This vibration started lately and i can't isolate it. I do know that i can make it happen by holding the RPMs at 1k. I feel the vibration pretty much everywhere but the seat and steering wheel is more. I know my balancer is on the verge but i knew that before this vib came out. I do have a Romac balancer on the way. It does seem worse in gear, but does have to be to feel it. Please help......

Is this a driving vibration or you feel it when it is sitting still? Check the integrity of your motor mounts.

motor and trany mounts would be my guess...i would get a new harmonic ballancer becuase you know that is going, then see how it feels and if no then you should get new mounts....right now i have a poly tranny mount and stock motor mounts....what every you do DON"T DO THIS....i have new poly motor mounts in my back seat just no place to install them.

Thanks for tip about the motor and trans mounts. Are they hard to install??
