Upper grill trim nightmare

[Luci007]

I’m having a nightmare with the upper grill trim on my T6, nothing seems to fit.

I got gloss black grill trims from THQ but no matte what I did they wouldn’t fit - even removing excess on clips etc.

I’ve now got a set from Veedub and they also don’t seem to fit. Is there some trick I’m missing to get them to go on?
Thanks
