Diffuser not sitting right

[Yoshi]

Hi guys,

I've had a rear reiger diffuser fitted but one side seems to be slipping out by 1-2cm ide say. Ok if I push it back on for a few miles but then slips again. The one side fits fine.

Not sure if I should use something to help it stick when pushed back in?

There's 3 screws holding the diffuser between the two exhausts but nothing between the exhaust and outside edge of the car. I know usually there is 1 screw each (between the exhaust and the outside edge of the car), there is on the original diffuser but can't actually see a hole to screw into even if I drilled one into the diffuser.

Any ideas?

Can you take it off and make a hole for the sides and put a screw in each side?

Can't see anywhere which the screw would go through to.

I have been recommended tiger seal so ile try that where i've circled on the photo then push on and leave for 24 hours.
