The rear brace (as Ford calls them) on my 2005 mustang convertible have rusted away completely. These are the two 5 foot rails or frame supports that are on convertibles only and run from the rear of the gas tank up towards the front on either side. I picked up a couple replacements in AZ when I was in Phoenix but I am wondering how much of a pain it is going to be to replace them in my driveway. Has anyone from a northern climate replaced these and how rusted in where the bolts etc.
