i have a few of my plastic nut caps missing so i ordered a full set off ebay oem caps from lincoln audi but i tried to fit them and cant push them on i expected them to be tighter than the old ones but not this tight i contacted them and they say they are all the same size but to get one on i had to bang it on and nearly broke the removing tool trying to remove it , so i didnt want to force any more on , can anyone tell me if this is correct?
