Moving gear stick

[mr302xd]

Hey all

I just got my engine mount done and ever since, the gear knob, while ur accelerating hard and going over bumps the gear stick moves all over the place. Ive had both engine mounts now replaced in the last 6 months what else could it be?
Also there is a clonk/banging noise when hitting bumps semi hard. Is there and gearbox mounts or sumthin like that could cause this??

All sugestions appreciated

Cheers Frank
