I'm fitting up my wheel arches (for the millionth time) and for anyone who has monte carlo / wood and picketts or whatever, how many screws have you got on each arch?

The arches hold pretty good with four screws, but I'm thinking six would be a bit better.
Anyone has any problems with them coming loose or anything?

I know the solution sounds as simple as put in lots, but I'm finding with every screw that goes in, the arch flexes a little in the opposite way and gaps appear, not to mention I want the least number of holes in my car as possible.

Thanks.


EDIT: Have five in there now and seems good, solved flexing by opening the holes up a fraction and twisting where needed with a heatgun.
