Run the car without the front mount then mate.
If your meaning the front offside mount that is circular.

Most people who fit a zetec to a non rs1800 shell dont have that mount and all cvh engines run the rear mount + 2x gearbox mounts not that front mount


Or order the part like i did and then pop to your local garage at the weekend and have the part pressed out and new one fitted cost you £10 max if you ask nicely.
