Funny - I have the same exact problem. Some idiot put a deer on the hood of this rig and it's antlers tore the body to smithirines. It's now mangled pretty good. Trouble is you need wipers to pass emissions. The rig's going in to a body shop in the next 30 days or so to get this repaired. They're going to cut out the old metal, weld in new metal, surface it, put the hole where it's supposed to do, reinstall the wipers and hope for the best...

I'll let you know how it goes. They quoted $400 for the work.

Change your oil hot and often.
