Strange Winding Noise and Vibrations

I just had the synchros re-done in my T5. I recently drove the car and when I accerlerate at higher RPM the car vibrates very bad(top of third gear) and I hear a loud winding noise(sounds like its coming from the engine).

The winding noise is only under hard acceleration at higher RPM usually it seems towards the end of a shift or basiclly under alot of load.

The Vibration gets worse at at the end of Third and continues up but it is present if I am accelerating through all the gears.

1991 Ford Mustang 302 5 Speed Tranny.

Any help would be greatly appreciated and thanks in advance

Will do, I asked some others as well and there was a 100 different scenarios, most included the shaft, others were balancer, wrong flywheel, and some other odds and ends.

I will look into the shaft,

Thanks
