Re: rivets vs self tapping screws
i really hate to disagree, but i have put self tapping screws on the exterior of busses for 25 years, and have not had any of them fall out that i know of in my previous 4 busses. I even have some on this bus - along with rivets as well. Regular sheet metal screws if the hole is driled the correct size is far better than the self tapping ones, but takes way more time...
Just my experience..
