So I've got a 2007 Ford Econoline E250 that I need to replace the drivers side sun visor. I have the replacement visor, but my problem is that I can't get the bolts out. Yes, bolts. Most videos & how-to's I've see show the visor attached by screws, but mine are attached by bolts. From the research I've done they look to be 4.2 x16mm. I can't get any of my ratchet attachments into the space to turn them. Is there a special tool needed or anyone have advice?
