Dress up bolts and fasteners
 

A friend of mine somehow has a broken bolt for one of the fasteners of the air box.

I am wondering if it is easy to remove the bolts around the air filter (see picture). I know you can remove the nuts but are the bolts welded in, making them difficult to remove?

I saw these for him to replace the bolts and all of them.
