Is it worth getting another dog bone mount?
It's recently had:
Both wishbones
New gearbox mount
Serviced
Rear pad
Tracking and camber done
Front wheels balanced
Like I said there's the issue that could be the driveshaft but I'm not 100% sure if that could be it.
It feels fine 1st, 2nd and 3rd. More towards the end of 3rd (50mph) and the beginning of 4th and 5th is when it starts rather bad.
