what exactly needs modifying on them to fit

i know youhave to trim them down for the grill to fit

but what about

the lower strip as my strip doesnt exactly fit right on them

where the 3 prongs are on the strip the middle one has a little catch

well that catch doesnt come out any where near the hole on the cover

does the bump on the cover need trimming back so it locks in or

am i just being picky
