rightwhen i bought my car it had a stainless steel petrol cap which i dont like tbh:

im not too keen on it and would prefer a nice original posi blue one, however the stailess steel one actually comes off when i undo the cap so if i was to buy a a stadrad one with the hinge how would i fit it?
also i would have the problem of the key for it
